Trimmer runs then stops
I have a Homelite F3055 timmer/brushcutter that starts fine cold and hot. It will run for about 30secs then stops. As it warms up it runs for shorter time. I have had it to the local repair shop and they say all is OK. It will run OK if not put under load. It is 2 years old and had little use. Thanks.

you had it at a shop that said 30 seconds run time is ok? those guys must have small yards . try the simple first. replace the fuel filter. inspect the fuel line while you're there for kinks or crushed sections. as long as it's starting the way you describe i'd say the carb and ignition are ok

Also try loosening the fuel cap when it starts to die. If that keeps it running, then the fuel cap vent is restricted.

I tried unscrewing the fuel cap a little today...& it seemed to help. It also spills fuel as the tank sits flat when in use. I don't know if the fuel cap has a vent ( it has a round white spot in centre)??? As I said It runs fine as long I don't start cutting.

If it runs fine as long as you're not cutting, that's a little different. Look on the side of the carb at the 2 mixture screws (side by side). Try loosening the one closest to the air filter 1/8 turn or so and see how it does.

I tried mixture screw backed off 1/8 and it did cut for about 4 min then the old problem was back. Always starts first pull..but then runs about 30sec. Sometimes if I am quick on the trigger I catch it before it stops and let it idle again.
Thanks alot for your interest and help.

I would go ahead and rebuild the carb. Sounds like your local small engine shop is well....
elevator doesn't go all the way to the top, but tear it apart, get a gasket kit and diapragm, and blow it out good with a can of carb cleaner using the little straw that comes with the can. I've gotten some going right by just doing this.
And to add, if you have a camera maybe, digital? take pics throughout, so to have something to go by in case you forget where something goes.

I agree, time to clean the carb. I'd suggest installing a rebuild kit in the carb, and when cleaning, pay particular attention to the inlet scree in the carb to be sure it is cleaned well.
