Hello noonotyes,

The cost of a carburetor kit would probably come close to the cost of the a new carburetor,part number 308054013. I would guess that is why the manufacture does not offer the kit. One other thing you might want to order the gasket for the carburetor depending on what model you have.

Hope this helps,

My question is the same. What is the answer?

Hello rongreen99,

It is becoming more common for the manufacture to replace the complete fuel tank instead of the fuel lines. And yes the fuel filter in included.

Thats quite the kick in the wallet.
I see where a Husqvarna gas tank is nearly $80 without hoses or filter.
The lines and filter are nickle and dime in comparison.

Hello spake3,

I think the choke lever you need is part number 518824001.

Probably a bad oil gas mix- use only 93 or 94 octane. Redo your gas oil mix "perfectly" exactly as oil mix label says...don't guess. drain the gas- push the bulb a couple times... clear it out. put in new gas- push the bulb a few times- start...keep pushing the bulb to push the new gas through. should smoke a little then should smooth out and run fine.

That reply did NOT answer the Question. I have the same problem. I replaced bulb also and still have prob and seeing you have changed the fuel lines (which i was thinking to do next. Thought it may be sucking air). I now have to go to the carborator. Dont think there is anything else left. I actually thought it may be the little black plug under the bulb releasing the fuel prematurely.

get a new carb... this new and improved gas with the ethanol tends to varnish and stop it up. if you cant get gas without ethanol, when done using pour remaining fuel out and run trimmer until it uses the fuel remaining in the carb and fuel lines.

Hi wilkie217,

By far the easiest way to replace the fuel lines is to simply replace the tank. The tank assembly comes with the new lines installed in the tank and a new fuel filter. For the small difference in price it is definitely the way to go.

I hope this helps,

Ryobi makes a kit that includes a ringed cable assy. to snake the included new fuel line and filter assy. as well as the breather line. Kit # AC04101

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.

Hi tomuch4head,

The clutch is part #00242. There are two plates required for your trimmer.

We have an article and video that will show you everything you need to know to install the clutch plates. You can find it here...

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.

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.

Hi Robert,

The fuel lines form their own seal where they pas through the tank. I would suspect that your fuel lines are old, hard and brittle which is allowing the fuel to spill. Their really is no way to replace just the lines on this design. The new fuel tank assembly comes with the lines pre-installed making for a simple repair. It is part #308181005.

There are two lines for the priming system. The feed line is the one with the in-tank filter on it. It is the one that feeds fuel into the carburetor both while priming or running. The other line is the return line. When priming the carb only uses a small amount of the fuel that flows into it. The rest is returned into the gas tank through the return line.

I hope this helps!

Hi Ron,

Sounds like a clogged carb to me. The passages in the carb are so small that the only way you can really clean it is by disassembling it. This is a bit of a risk on your Ryobi carb as Ryobi does not offer a rebuild kit to replace the inner pieces of the carb so you must be very careful while taking it apart. We cover this repair in the following article and video...

http://www.ereplacementparts.com/article/4582/How_to_Clean_a_2_Cycle_Engine_Carburetor.html

The other option is to simply replace the carb. It is part #308054013.

Hi Frank,

The special screws on the carb adjustments are there due to the new EPA restrictions on 2-cycle engine emissions. The manufacture must certify that their engine burns fuel within the EPA requirement so they set that carb at the factory and then make the tools available to their network of trained service centers. Your best bet is to take the trimmer to your local authorized service center and have them make the adjustments for you. Another benefit of letting the shop make the adjustment is that serious damage can occur to the engine if it is adjusted too lean. The service center will ensure that the carb is not set too lean.

Good Luck!

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!

Use a torx 25 screwdriver at least 3" long down the center of the clutch housing.

[QUOTE=anonymous;45739]The primer bulb on my BC 30 Trimmer has a hole in it. I don't see one listed. Do I need to replace the carburetor?"

What did you do? Mine has hole as well. I dont want to purchase the entire carb..

Google ZAMA CARBURETOR PRIMER BULB you will find your replacement. I bought one new a my local mower repair shop for $2.27 (that's with tax) and it works just fine.

If the adjustment needed is to stop the trimmer head, then the answer is go to the idle screw on the carb. Otherwise there is no adjustment, it is strictly a centrifugal clutch.

It may be that you need to take the screw out of the clutch drum. I believe it is a Torx 25 in the same place the drive shaft came from. Once the drum is off the clutch need to be removed. Lock the piston and remove the clutch in the direction printed on the clutch. It will take a sharp blow with the piston locked to remove the clutch. Now the recoil housing can be removed and the starter spring will be in this housing.

Hi Larry,

It sounds like a clogged carburetor to me as well. There is no carb kit available for this trimmer. You will need to simply replace the carb. It is also a good idea to replace the air filter at the same time. The carburetor is part #308054003 and the air filter is part #98760. Both are available from http://ereplacementparts.com.

Hi Richard,

No spark is usually an indication of a bad ignition coil. I would first check for spark with a spark tester. If the spark tester confirms that spark is not present then the coil will be the problem. The ignition coil is part #850080001 and is available from http://ereplacementparts.com.

I hope this helps with your repair!

Hi Pauric,

If the trimmer is hard to start but then runs OK once started I would consider doing a tune up. To do a basic tune up you will need to replace the air filter, the fuel filter and the spark plug. It is a good idea to do a basic tuneup at the beginning of each season.
For your trimmer you will need the following parts...

Air filter - #98760
Spark Plug - #870174001
Fuel filter - #530091878

Ryobi only offers the fuel filter as part of the gas tank assembly. The fuel filter listed is from Poulan. In tank fuel filters are pretty universal and the one from Poulan should work just fine.

If the engine still doesn't start easily and run well after the tune up then it likely has a clogged carburetor. the carburetor will need to be replaced. The carburetor can become plugged with dirt and other debris. If gas is left in the tool for more than a couple of months it will breakdown and turn to a varnish in the carburetor. This will also plug the carburetor. The carburetor is part #308054013.

All of these parts are available from http://ereplacementparts.com.

Good luck with your repair!

Hello,

The new rotor has a key cast into it that should line up to a key way on the motor. With the key and key way aligned the rotor will be in the proper orientation for proper timing.

Hi Loc,

I think you could solve the problem but it would take a bit of modification.

The end of the bolt opposite which the knob is attached to has been mushroomed so that it can't come loose and be lost. You will need to grind the mushroomed part off so that the bolt can be removed. Take the bolt to a home center with you. Find a flat washer and a rubber washer that will fit the bolt. Slide the rubber washer on the bolt first followed by the flat washer. Now reinstall the bolt onto the trimmer. The rubber washer should provide enough cushion and grip to keep the knob from coming loose.

I hope this helps!

Hi Jim,

Fuel line and filter can be purchased at any LM repair shop. bring your tank with you. Buy about 2 feet of fuel line. remove old line. CUT ONE END OF NEW LINE on a bevel (point) Force it through the hole in the tank closest to the filler cap with a twisting motion (clockwise) until the end comes out the filler cap enough that you can trim the bevel off and put the filter on. Pull the line back through till filter is laying flat on it's side in bottom of tank. Trim to length and attach to carb. Treat other line likewise..A little oil on line helps to get thru hole in tank Filter 3.00 line 2.00 per foot

The rope on mine jumped off the starter pulley assembly and got looped around the tabs on the baffle (part 41 above). I had to take it all apart to get the rope re-wound. Just be careful of the rope return spring and container! The above diagrams are very helpful. To get the Drum and Connector (part 33 above) off, you need a T20 screwdriver, about 3 in long and something to keep the piston/rotor from turning.

Do the clutches screw on or slide on?

Your not going to belive this. My pull rope only came out 6 inch. I took it apart to find out why. What I found was a sand dabbler (wasp) created a nest. It was between the ignition module and the rotor. Cleaned it up pulls fine now.

Yes, there is a screw in the shaft of the drum. It is a Torx, and it is very tight until you snap it loose, so be patient, and strong! When you try to take the clutch loose, it is even tighter. I used the rope in the spark plug piston area trick. If you try to jamb something in the fin area, you will just break something, so be careful.

It could be a Primer Bulb, I see them on eBay WOEM PRIMER BULB WALBRO 188-512-1 RYOBI 683974 188 512 for about $6-7 shipped. It probably has a hole in it.

to get to the ignition coil itself you need to remove the power head from the shaft.
remove the clutch drum, then the clutch springs. then the outer housing will pull away from the engine block exposing the ignition coil and plug wire.

yeah I'm having the same problem... looks like there is a screw inside but it just turns the motor over... I have no clue let me know when if you figure it out before I do!!

hey I got it!! check out this video, very helpful!

[QUOTE=Sndman;69654]Have had Ryobi and John Deere Brushcutters for years these 2 have run great until stored this past year. Both can be primed through the carb inlet and will run until that fuel is gone. I replaced the carb and gaskets and the same problem persists. Tank is clean fuel is new at 50:1 with stabilizer. filters are all clean. exhaust has no issues since it runs when manually primed, Can some explain why the fuel from the new carb isn't getting to the motor?"

I would check for hole in line in the tank, make sure filter on gas line is clean, if you have primer bulb check for cracks.

I have found that the barrell sometimes comes loose from the crankcase. It then runs lean, as it sounds yours is. Strip down and replace it otherwise the barrell will be quickly ruined.

there are 3 bolts at the bottom of the cylinder
one sometimes breaks
dismantle the engine
remove old bolt
and replace with a new bolt
while your there check out your piston :cool:

poindexter why do you say you need a special wrench usually the jets are just slotted;sometimes the manufacturer puts on a plastic piece so you can only turn the jet each way very little;you may be able to pop the plastic end off to get to the jet adjustment screw;why do you want to adjust the mixture jet anyway???????????

Same problem here. My trimmer ran well for one season. It started the next, but the screws came loose on the carburetor assembly. The machine has given me trouble ever since. I bought a new carb and it ran for awhile but then quit again.

Exactly the problem that plagued my machine. How about a recall on brush cutters?
I even followed the maintenance procedure of running fuel additive for storage and that didn't even work.

You are all exactly right! I have bought Ryobi before but never again! This thing won't run at full speed anymore. Very frustrating.
