probably a broken clutch. just had that issue myself. one of two clutch springs snapped. temporarily repaired with tie-wire. hey it works for the mean timel (also spring cant be bought alone)
WJA
Reply: Head Unit Won't Turn

WJA

Hello,

There are a couple of other items to check also along with the 753-1238 clutch. Make sure your drive shafts are connected and not worn on the ends. They would be part numbers 791-181852 lower flexible drive shaft, 753-04503 boom assembly (the upper drive shaft is in side of it). And check the clutch drum assembly, it may be rounded where the drive shaft goes through and it may be worn to thin for the clutch to make contact.

Question: Trigger Assembly

Bwilly

My Ryobi 825r will start but when I pull the trigger the engine does not respond and the trimmer does not spin. I think its the trigger assembly and/or the trigger cable. Are my assumptions correct? Am I missing something else? And is this a repair I can do myself?

Question: Primer Bulb

When replacing the primer bulb several parts of the carburetor came off. I thought I put them back on the correct way but now all the trimmer will do is idle. When I give it gas to start trimming it dies. Should I replace the whole carburetor kit?

Reply: Primer Bulb

UtahAV

Hi dayoung,

I would start by cleaning the carburetor. We have an article and video available that will show you how. You can find it here...

How to Clean a 2-Cycle Carburetor.

If while cleaning the carb you notice that the diaphragm or the reed valves seem hard or brittle then you will need to install the carb repair kit.

I hope this helps,

Hello:
Noticed recently lower shaft housing is slipping in the click-link connector. - and although motor runs at high speed - get no joy at trimmer or acces. end. Part #753-0453 does that include female type fitting (not rounded out)? Is it repair I can make?

Question: Upper Drive Shaft Housing

Is this just the housing or is the driveshaft included. My housing is fine, but the drive shaft is stripped and will not turn the lower shaft.
UtahAV
Reply: Upper Drive Shaft Housing

Hi lakecam,

The shaft assembly includes both the outer shaft and the inner cable. It can only be offered this way because there are some connections on the inner cable that can only be made by the factory.

* Engine is 793-00007 aka AC-2.1, 26.1cc
* Fuel Line 0.080 ID, same as poulan 530069247. Tygon is better.
* Carburetor is Walbro WYL-187-1 aka Ryobi/Ryan/MTD 753-1225
* Carb Diaphragm kit is D11-WYL
* Carb Metering spring is 98-3160-7
* Carb Rebuild is K20-WYL or Ryobi 753-04014.
* Primer Bulb is 188-16-1 (originally 188-12-1)

Question: Carb

Adam

My trimmer wasn't running, and the fuel lines were bad so I replaced the fuel lines and fuel filter. Trimmer still didn't run. Realized the problem was in the carb. After looking at prices for a replacement, I decided to take my carb apart and clean everything. I paid special attention to the small holes and the diaphragm spring pendulum thing. I found that the diaphragm was getting stuck. After I took it apart, I scraped and cleaned it, reassembled the carb and voila! the trimmer runs again. I don't know how long this fix is going to work, but it saved me $66 so it's worth it to me. Hope this helps.
Barry Levy
Question: Attachment Point Failing

Barry Levy

Hello: I own 825 4 cycle Ryobi trimmer. It has had fairly light use over about 3 yrs. Now the attachment coupling (female) is no longer sharply defined, causing attachment of various tools, including the original dual line trimmer, to spin slowly if at all. The motor is running fine. Can that coupling, one that comes halfway down shaft from motor, be replaced? Thank you
UtahAV
Reply: Attachment Point Failing

UtahAV

Hi Barry,

The coupling is part of the upper shaft assembly. The coupling, as well as some other parts, are permanently attached to the cable at the factory so they can't be replaced separately. The upper shaft assembly is part #753-04503.

I hope this helps,

Question: Fuel Return Line Pick-up

Ken

My Ryobi has a black plastic and metal part that comes out of the top of the carburetor and attaches to the fuel return line. It looks somewhat like the breather tube assembly listed here, but it makes a 90 degree angle and is male on both ends going into the carburetor and the fuel return line. Is that the same as the part listed on your parts list. If not, can you tell me the part number?
DanielJ
Reply: Fuel Return Line Pick-up

DanielJ

I'm looking for the same thing. Mine is busted. I bought the fuel line with filter from this site but it does not come with that 90 degree piece. Do I have to buy a whole carburetor? In any case, even some photos of carburetor don't show that piece.

Question: Replace A Start Rope

Mike M

I have replaced the starter rope on my Ryobi. I put it back together and was able to start it. After I shut it down I was unable to use the pull cord to restart it. It was like it was seized. I took it apart again, put back together and thought I was ok. Same thing happened. Once I got it started I was unable to use the pull cord. Did I put it together wrong or is a part broken?
Is the drive shaft one piece from the clutch to the accessory?
WJA
Reply: Gas Trimmer Flexible Drive Shaft

WJA

Hi Gil,

The Ryobi trimmer actually utilizes two drive shafts in this unit. The upper drive shaft and housing assembly contains the drive shaft from the clutch and has a coupling on the other end to accept the lower drive shaft and housing assembly.

Hope this helps,

Mike Schmitt
Question: Trimmer Disengages.

Mike Schmitt

My trimmer attaches to several tools. It is disengaging from the various tools during use and the shaft is spinning inside. Is it missing a spring or something that would keep the couplings engaged? If I hold it vertically it will re-engage and work briefly. Then disengages again.

Question: Fuel Lines

owner

It appears that the trimmer is not getting fuel from the tank. There are three pieces of orange pipe in the bottom of the tank, not attached to anything. It looks like there is no serviceable parts in there. Do I have to purchase a gas tank and would that tank have all the necessary internal lines?
Mark
Reply: Fuel Lines

Mark

Hello,

You have two options well replacing the fuel lines. You can replace just the lines. The pickup line with fuel filter is part #791-182353 the fuel return line is part #791-182352. You could also replace the entire fuel tank. It includes both lines already installed. The fuel tank assembly is part #791-182355. All of these parts are available from http://www.ereplacementparts.com .

Good luck with your repair!

Question: Lack Of Fuel From Carb

I replaced my fuel lines and primer ball after finding cracks in them. My trimmer will start is I prime the cylinder with fuel but will not remain running. It will not start with this priming. What do I do?
Mark
Reply: Lack Of Fuel From Carb

Mark

Hi Nick-BG, I think the problem is going to be in the carburetor. When fuel lines become cracked it can let dirt into the carb. The lines breaking down themselves can also put debris into the carb. Replacing the carb should get things running again. It is part #753-1225 and is available from http://www.ereplacementparts.com. Hope this helps! -Mark

Reply: Lack Of Fuel From Carb

Mike

Nick, I was wondering how you got the intake fuel line with the filter on the end inside the fuel tank? Of course I could take the plastic intake line off the filter and shove the fuel line into the top opening then fish out the line and reinstall the filter, but I kind of hate to take the line off the filter because it fits so tightly and would probably have to be cut off. How did you do it?

Also, did you buy a new carb, or just clean the old one to get it running again?

when you say clutch housing you do mean the clutch itself right? (all metal)
take a hammer and punch. insert punch into center of clutch drum assembly. hit it hard 1 or 2 x. Might break it loose.
