What's wrong with my Ryobi string trimmers?
I have two Ryobi string trimmers, one is the older 790r model, and the other one is newer but not sure which model it is. They both essentially have the same issue... They crank up easy, will sit there and idle just fine, but once you try and give them any throttle they just want to die like you hit the kill switch. I had a suggestion on another forum to check the spark screen, so today I pulled the muffler off of the 790r and checked it. Well, it had no screen, and there was no clogging of the exhaust port either. So, any idea's what's wrong with these two trimmers? Thanks!
