Okay this weedeater runs perfectly and will start every time the first pull. But when I use it continuously for 15 minutes it will not take throttle any more. After it cools all si fine again. It will idle fine after heats up but cannot accelerate. Any suggestions what to look for?

Yes it accelerates great until I run it for like 10-15 minutes then it want take throttle anymore. Let it cool and all is well again.

what happens when you try to accelerate after 10mins?

It will just bog down and die. It will start right back up at idle but want take any acceleration still.

i had a 2 stroke do that to me and it was my air rfilter and bearings in bottem end were bad

yes =) i agree with blaake, but if it accelerates at the beginning that excludes the filter and bearings... is the gas old? are you using right mixture? check spark plug right after it cant accelreate, what color is it?

This is a 4 stroke trimmer?
Look for an air leak that develops when the engine heats up, perhaps the carburetor insulator is loose, possible valve lash needs adjustment.

>( ouch... i guess i didnt read the title, yes its a four cycle.

ck the breather that goes from the crankcase to the carb air box. ck to see if the duckbill is clogged. this tube releases crankcase pressure on the crank case.

i agree with u blackwell that makes alot of since that the crank case pressure is building up thats y it works at beginning and not after 15 min
