Question: Ryobi BC30 Pull Cord Stuck

LoriG

Ryobi BC30 - I was using my brush cutter attachment when it suddenly cut out (although I did not think it had been running very long or too hot). Anyway, when I went to restart it, the pull rope was stuck and I could not pull it out. I disconnected the boom, hoping it would free up the cord, but no luck. I have reviewed the online video regarding clutch removal/spring replacement (very helpful), but have not yet attempted it as not sure I know what to look for. Plus not sure if piston itself has seized. I'm a female and not the most mechanically inclined, but want to learn about this, as well as maybe save me the cost of a replacement unit. Can anybody tell me what to look for and how to diagnose starter issue vs engine issue? Thanks, Lori
Hi Lori, To diagnose a starter issue vs. an engine issue; most times the machine has to be disassembled. That job is a very tricky and tedious. I have seen them do like yours and have a broken part of the engine FRAME caught in the flywheel, jamming the engine. Sometimes an engine seizes up also due to mechanical failure or improper gas/oil mix. Sometimes the rope INSIDE the starter pulley breaks or comes loose and gets jammed up in the starter housing. Removing the starter on a RYOBI is a cumbersome job. It can frustrate even mechanically inclined individuals. Most folks can take things apart but cannot reassemble. I mean NO offense, but can you maybe have a guy you know that IS mechanically inclined look at it? I have found with these weedeaters, that the cheaper they cost...the HARDER they are to work on; and that is a fact as I have repaired dozens of them.
ShotOut, thanks for the reply - much appreciated. The strange thing is I have battled this trimmer for a couple years now regarding startability and when it failed me again using the brushcutter, I purposely dumped out the old gas tank and refilled it with a fresh 50/1 mix and it ran flawlessly for a few times, then failed as noted above. I'm a chem engr, can handle corrct math, and certainly know the implications of running an engine with incorrect gas/oil ratio so not sure what happened here. I have the unit half-disassembled now, but my torx is too short to remove the clutch drum, so will work on later once I have access to correct tools (I actually do have some mech ability, but tore a ligament in my thumb (UCL) a couple years ago, so watching that guy manipulate his hand to tie the knot in the video is not doable by me as I have lost some dexterity there, I would need a third hand as he intimated). I can see the rope wrapped around the pulley and it looks fine, so probably seized the piston. Out of curiosity, would you recommend swapping in a new engine or just trashing the unit? And secondly, since you mentioned that you repair these frequently, can you recommend a brand and model should I elect to replace? Thanks again, Lori
Hi Lori I am glad you posted back. I utilize sales on ebay for replacement engines when needed. Sometimes all they need is the cylinder lightly honed (with like 600 grit Wet/Dry paper) and a new piston ring. Repowering one is much cheaper than buying another machine. Ryobis are extremely popular but are NOT the cheapest machine available. I hope the piston isn't seized.
That clutch drum has that dumb T-20 screw down inside it, it will loosen, but it is not designed to be completely removed.Sometimes they are REALLY tight, and if so, spray some penetrating oil down in there. Like I said, disassembling a doggone Ryobi is NOT childs play, but if you do it, you will have learned something. If you can work on and repair a RYOBI, you can work on any of them!
I suggest trying to get to at least the starter pulley on the thing, and since you are 1/2 way there, might as well keep going! They have diagrams on these things if you get a little confused putting it all back together! Or post again, and we will try to help.
IF you elect to replace I strongly suggest an Echo trimmer. They are reasonably priced, are super reliable, and come with a 5 year consumer warranty. The curved shaft machine is usually cheaper than the straight shaft. I have a vintage Echo 19cc SRM-240 Brushcutter from the 80's or so that still runs, although it did get a new piston ring! You cant go wrong getting one of their units. If you need more help with the Ryobi, I am here.
Okay, hoping for add'l hep and advice on if I screwed up severely. So I found a T-25 Torx with a long enough shaft and removed the clutch wheel. I thought that the two plate would pop off as per the video, but not so. Screw up #1 - bent the outer one trying to remove it and then realized that it threaded off counterclockwise (normal) but cannot seem to get the inner clutch plate off (it appears to be stuck against that back retainer plate somehow). Should it pry off as per video, or, if I need to unthread it and, if so, which direction? I still have the rag stuck into the cylinder so I do not think that the shaft is rotating any. let me know. Thanks a bunch, Lori

Also, can I rebend the clutch plate back into its original form or should I replace it?
Okay, I'm now back to my original question - how do I properly diagnose between starter issue and engine issue? I took everything apart last eve, pounded out the bend in the outer clutch plate with a rubber mallet. When I removed the starter pulley, the spring sprung out of its holder (tension released),so at first I thought it was a spring issue, but now thinking about it more and thinking that I did that when I removed the pulley. I'm pretty sure that I can order a new spring, but still not sure if that will correct the initial issue of engine cutout and cord seizing. Thoughts anyone? I'd be appreciative...
Lori, With the rag in the ENGINE removed, can you rotate the shaft? If so, no LOCKED UP engine issue. The parts on the starter could be worn, because most of it is nylon and plastic. Glad you straightened the retaining ring. Normally, on a Ryobi starter, there are a few little screws keeping a retainer on the spring to keep it from popping out. It is ONLY necessary to remove the entire unit and then inspect it. It is NOT recommended that it be disassembled while still on machine. Check the moving parts of the cheap starter...then check the moving parts of the engine. Diagnosis done.
Engine cutout could be due to an intermittent coil, overheated ignition coil, and/or carburetor issue.

Question: Curved Shaft Grass Trimmer Exten...

roperdoug

This is off a Ryobi BC30 Trimmer that I'm rebuilding. This model has the TrimmerPlus extension shaft but I don't think the curved shaft originally came with it nor do I think it is a TrimmerPlus brand unless it's discontinued. I found the spool (one on it is damaged) but looking for the correct model number to get the right guard for it. The guard attaches to the head by screws.

Question: New Fuel Lines / Fuel Filter

dantheblackman

I was doing some work on my machine, and my fuel line which connects the fuel filter inside the tank and leads to the actual engine/bubble primer broke.

Does part 0143910 function to carry fuel from the fuel filter inside the tank to the bubble primer?

If not, is it possible to buy that fuel line and the fuel filter apart from the entire fuel tank assembly?

Thanks.
WJA
Hello 1190351,

If you look at the parts diagram for the UT-20699 trimmer. Go to page A, and you will be able to see that the fuel filter and fuel lines are available for purchase. Once you have the lines you wanted to purchase we have an article and video on How to Replace Fuel Lines on 2-Cycle Engines.

Hope this helps,

Question: Ryobi BC 30

jswarner1

RY30004.. Zama Carb. The plastic restrictor attachments to the Carb. Overhauled and replaced questionable components but need to adjust fuel/air mixture. Do those plastic restrictors just slide off the splined post they are on or are they attached somehow? I need to adjust the carb. and only way to do that is without the plastic restrictors still on the carb. Point of the question: Can I safely remove the plastic restrictors by sliding them off the splined shaft or is there a locking mechanism that holds them on????
Thank you. I find the BC 30 to be a great machine except when EPA gets involved, like other government agencies, and gums up the works.
WJA
Hello jswarner1,

EPA Carburetors

Your machine has an "EPA" carburetor. Starting in 1997 The EPA placed requirements on how clean small engines are required to burn. As part of this restriction the carburetors are set at the factory. The carb then either has the adjustment ports capped or they use special adjustment screws so that the carb can only be adjusted by a tech trained in compliance with the EPA directives. The manufacture offers the special carb adjustment tools their authorized repair shops but not to the general public. The manufacture is liable to ensure that the equipment they sell complies with the EPA directive and therefore will typically not offer the adjustment tools for sale to the general public. You can learn more about the EPA emissions requirements for small engines at the following link...

http://www.epa.gov/otaq/consumer/f98025a.pdf

Before you adjust the carburetor you should determine why it needs adjustment first. A carb should only need adjustment when it is new and needs to be adjusted for altitude or after a carburetor rebuild has been performed. If a piece of equipment has been working fine and then starts acting up there will be more repair issues than a simple carb adjustment. The carburetor itself will not simply go out of adjustment. You will want to look at things like a tune up, a clogged carburetor, a plugged exhaust system, ignition problems, etc. Adjusting a carburetor requires some knowledge and experience with small engines. You can easily overheat and seize the engine if you are not familiar with the proper procedures. It is also a good idea to use an engine tachometer to be sure that you make the correct adjustments.
Question: Replacing Clutch Plates

speedycoche1

Hi, when I took my trimmer apart, both of the clutch plates were broken and basically fell off the shaft. Is there a specific direction/orientation that the new clutch plates have to be installed in? I've already ordered 2 clutch plates. Thanks!
WJA
Hello speedycoche1,

We have an article and video on How to Fix the Starter on a Ryobi Trimmer. It will show you and tell you how to remove the clutch plates.

Hope this helps,

-WJA
Thanks for the response, but I already watched that video. It was quite helpful in taking the trimmer apart to access the clutch plates and diagnose the problem. When the new clutch plates arrive, is there a specific way that they have to be put on? Is there and 'inside' and 'outside' face, or does the way they face not matter? Thanks!
WJA
Hello speedycoche1,

Once you receive your new clutch plates. You will notice a round notch on one side of the clutch plate. Replace the clutch plates with the round notch facing out.

Hope that helps,

Question: Ryobi BC30 Piston And Cylinder D...

tjhopler

Hi everyone,

I'm new here. Bought a Ryobi BC30 at a garage sale for $10. It hasn't been used or maintained in about 2 years and was not prepared for storage at that time.

Pretty much every gasket was shot from the effects of time and the residual gas/oil mix sitting in it. While preparing to replace the cylinder gasket, I took out the piston and noticed its been damaged. The damage only affects about a third of the cylinder/piston. If you're facing the cylinder from the carb side, the damage is on the left side of the cylinder.

My question is... when reassembled, will this poor beast run at or reasonably close to normal performance, or will it just commit suicide?

I've attached a pic of the piston. I can't get enough light to snap a shot of the cylinder, but the piston seems to have taken the majority of the damage.

link removed
WJA
Hello tjhopler,

If you have replaced the gaskets and the engine still runs, by the looks of the piston I don't think your going to have much compression or power. You may want to run it till it dies on you. Or at least you I would guess you are going to need a new 985872001 piston and a new 985524002 cylinder.

Good luck,

Question: Spark Plug Wire

russhughes

do you carry replacement spark plug wire for a Ryobi BC 30?
WJA
Hello russhughes,

The manufacture does not supply just the spark plug wire only. The complete ignition module would have to be ordered. It is part number 850080001.

Hope this helps,

Question: Carburetor

paulrichmond

are gaskets and/or overhaul kits available?
Yes, they are. Your exact carburetor application is the key. If you have the Ruiing carb without the choke lever instead of this Homelite carb, Zama carb parts fit it. One or two kits for it are on Ebay. There are also kits for the Homelite carb, but I can't tell if it is the Ruiing or Zama.
Question: Ryobi Weed Wacker

mjpia295

I need two parts. The first is the knob to set the choke. The second is the tool to adjust the mixture.
WJA
Hello mjpia295,

Unfortunately the manufacture does not supply the choke lever as a replaceable part for this unit. The complete carburetor would have to be replaced. It is part number 308054013 . As for the tool to adjust the mixture, they are probably only sold to the authorized service centers as a special service tool. I have seen quite a few engines damaged because of a fuel mixture that's too lean. If not set right it can take out a engine within minutes. You might want to use a qualified small engine service center to make that adjustment for you.

Question: BC30 Ryobi Trimer

Xuat

My BC30 Ryobi trimmer can start, but when I move the choke lever to run it dies out. I installed a new fuel filter, put in new gas mixture, and a new air filter but the problem still persists. Can someone please help with this?
Hello,

It sounds like you probably have a clogged carburetor.

The carburetor can become clogged by dirt or other debris. The dirt may get by a damaged or missing air filter. It can enter through a crack in the fuel lines. Some tools use a foam air filter. Over time the filter itself will breakdown and create debris that will enter the carb and clog it. It is a good idea to replace the air filter at least once a year. If fuel is left sitting in an unused engine for more than a couple of months the fuel will begin to breakdown and go bad. As the fuel breaks down it will start to become gel like as well as begin to coat the internal parts of the carburetor with a varnish. The gel and varnish will plug the carburetor so that fuel can no longer flow through it. To get your engine running again you will need to either rebuild or replace the carburetor. When you replace the carburetor it is always a good idea to also replace the air and fuel filters. This helps ensure that more debris won't clog the new carburetor.

Ryobi does not offer a carburetor rebuild kit for the carb on your trimmer. Your bet bet is to simply replace the carburetor. The carburetor is part #308054003 and is available from http://www.ereplacementparts.com .

Good luck with your repair!

-Mark



Mark makes good points, but....over time, the teflon or mylar fuel pumps in these dry out and do not pump fuel anymore. That is WHY they will run on full choke only and die, because that is the only way the mixture is RICH enough to allow the engine to fire and run.There are gasket and diaphragm kits for most ALL small carbs like this and there are rebuild kits as well...which include all the parts in a GND kit, plus some link removed these does NOT guarantee it is fixed however as check valves in these units tend to get stuck and/or damaged with chemicals.
Ryobi does NOT make carburetors or repair kits for carbs to begin with. They use carburetors manufactured by Zama, Ruiing, or Walbro. There ARE rebuild and repair kits available for most ALL diaphragm carburetors and a kit is MUCH cheaper than a new carb...unless you get one off of eBAy from a China seller and don't know if he will ever send it to you or not. I ought to know as I have been repairing these small carburetors for years!
