Trying to fine tune my first fourstroke...its a .91 ThunderTiger and I just can't quite get it to "slow down"...or idle I suppose would be a better word. My guess is its too rich but before I fiddle with it I wanted to get some feedback. I've fiddled with it before and only made it worse. It cut out on me in flight and the results were not pretty. My RPM tester gets as high as 7000 and that is it. Engine manual says it should reach as high as 11,000. Too rich?
Thanks!
