Ryobi EX 26 2 cycle

On my 3rd year with this machine, this year however is giving me problems. It will start fine on full CHOKE, it will run @ 90% on the HALF setting, however when I put it on RUN the engine will bog down and stop. If I move the carb lever back to the HALF setting it will sputter and continue to run. Things I have done so far: visual inspection of carb, engine has no air filter screen looks clear, removed the muffler, cleaned it out with carb cleaner, removed spark plug, cleaned with carb cleaner, looked normal? gave the carb several shots of carb cleaner and let it soak for a while. Restarted normal, runs on half, although not the normal responsive "I am ready to get after those hedges/weeds etc sound " move to RUN position, seems to run only on full throttle, leave off on the throttle and it bogs and stops. New fuel and mixture. So I am guessing the carb is the next thing to disassemble and clean? Any suggestions appreciated.

 

While it is running spray/dribble carb/brake parts cleaner behind the carb and along the mating surfaces, if the engine tempo changes you have an air leak and can take the appropriate action. Have a good one. Geo

 

Time to replace or completly remove and soak the crab and rebuild with new gaskets.

 

Spraying the base with carb cleaner, made no difference, but I have to put full throttle on it to keep it running. Hard to tell. Priced new carb on internet, $23 + $7 shipping. Would like to make that the last resort if possible. Noticed that the carb has "pack man style" adjustment screws on the carb looks like a PITA to adjust unless you have a "special" tool $14. Thinking I will have to adjust no matter what if rebuild or replace ?? TX for the suggestions!!

 

This is what I did.Take the carb. off the trimmer,and use a dremel tool with a cutting wheel and cut across the top of the carb. down to the adjustment screws, to make a slot so you can turn the adjustment screws with a flat blade screw driver.This will not hurt the carb.Turn both of the screws counter clockwise about a half turn.You should be good to go.

Good idea Jerry, will be trying that shortly. This is what mine looks like

 

That is what by carb. looks like.Now take the carb. off and cut horizonally across both screws until you make slots for a flat screw driver in the adjustment screws,.Like I said in the above post,it will not hurt the carb. if you cut the carb.I put the dremel tool in a vise and hold the carb. to make the cut.But you can do it either way,carb in the vise,but don't clamp down to tight on the carb.

Thanks Jerry. I had a similar problem with mine and your procedure fixed it. I was about ready to toss it and by a new one....
Thanks again,
