Ryobi BC 30 trimmer bogs down with throttle

I have a BC 30 trimmer that bogs down. It starts ok, but I have to let it warm up for at least 10-15 minutes. Even still, I have to go very slow on the trigger to get it up to speed and any heavy load stalls it out. I am using the choke correctly, with new gas/oil mix, and a clean correctly gapped spark plug. The other serious symptom is that if you tilt the motor left, it cuts out immediately and dies. It also begins leaking gas through the air intake. I should have returned it, but I took it apart instead. There are gas stains on the gaskets surrounding the intake, but they seem to be in place secure. All screws were tight. Any ideas? Thanks!

PROPER WAY TO START TRIMMER.


Pump the primer bulb on the carburetor at least 7 times....set choke lever ( the yellow lever on the air cleaner) to the down start position....pull start handle till it fires....let machine run for about 30 to 45 seconds before you open the throttle to give it a chance to warm up....that's it !!! ;-D

Check the metering diaphram and check valve in the carby.The valve might be leakin and the diaphrm might be hard. do a google on the make of the carby as these are fitted with a few makes manly Zamer but. DONT use compressed air to clean or automotive type carby cleaner all will kill the valve and its not replacable..

I have a Ryobi BC 30 trimmer. It runs fine but


Are you using the proper size line? Check the ends of the spool. It will give you the size you need. Also while you are checking, locate the arrow that shows the direction to wind the line. Hope this is of some help...Lee

I have a 31 cc ryobi weed eater start for about


I think a new carburetor kit and a good carburetor tune up is in order my friend. Sounds like it's starving for gas. If it bogs down after warm up when you throttle it, then yes it needs a carb tuning. The L screw is the low side screw and should be turned in lightly until it seats then back it out one and quarter turns (1 1/4). The H screw is your high speed screw. Also, turn it in lightly until it seats, then back it out approximately a 3/4 turn. With these settings the unit should start and may even stay running. Again, if it bogs when throttled, while running turn the L screw out a little more maybe only 1/16th of a turn and then try it again. If it does rev then you'll have to adjust the H screw in about a 1/16th of a turn. But make sure you only do this after the engine has warmed up.

Hope this works, good luck

Ryobi 720r trimmer starts ok but stalls when the


The carburator needs to be adjusted a little, thin our your mixture screw when the trimmer is warmed up and idling. Well how do you get it to idle? I usually have to play with the choke lever with the throttle wide open going from choke to partial choke as needed to keep it running. Adjusting can be tricky, you need a small screwdriver. Screw all the way in then back out 3 to 3.5 turns. this should get you close. Adjust idle as needed.

Ryobi cs30 starts fine, but idles way too fast after warm up. I mean screaming fast. Throttle return works fine and idle adjustment is set at it lowest.


you need to take your air filter off and look into the throat of the carbruetor to see if the ""Butterfly""
is still intact and working not the choke butterfly its the one closest to the engine that moves with the throttle and be sure it is still there and moves as you move the throttle.... open is horizontal and closed is not quite 90 Degrees. check to see it is tight and in the center if the throat when closed.
you may have to remove the carb. to see it function more clearly
make sure the throttle cable is free and not binding any where and to be sure of its adjustment to allow the throttle to return to the idle position.
lubricate the cable from the trigger to carb. wd 40 is ok.
if all above is ok then find the L on the carb. and ccw it 1/8 turn to ritchen it alittle to help slow the idle down some to a respectable level
