My Stihl FS 76 trimmer runs ok til it gets warmed up. Then, if I let off the gas for something, when I try to rev it up again it will not. It either falters and does not rev, or it dies. I've replaced the plug and cleaned the air filter. Haven't replaced the fuel filter, but since it runs fine til warmed up, that doesn't seem like the issue (to me). Any ideas?

Next day--Darn, I thought I might have had an idea--plugged gas cap vent, causing a vacuum in the tank as the gas level goes down, preventing gas from feeding to the carb after running for a while. But I tried loosening it for a second. No improvement---
Looks like 60 folks have viewed this w/out coming up w/ any ideas. A stumper, I guess---
