It definitely falls off to early, I'm pretty sure that the silencer needs repacked gonna do that tomorrow, it's still on the tank of gas that was in it when I got it, mixed with Klots 32:1, it don't seem to rich, no spooge out the silencer. It's got a pro design head also, I'm gonna check the plug tomorrow. I'll let you guys know what I find. I appreciate the quick responses, glad I found a forum still very active.
