Thanks for all the info.Got with my instructor tonight and used a OS A3 plug and got the thing acting decent. Got it pretty lean on idle mix and RICH on high mix. Ofcourse I wont get to put it back in the air until tomorrow but it acted pretty good on the bench. It actually idled for 10 minutes or so. Transition from idle to full throttle was decent and it held up pointed up, down or on its back. Will get by the H/S and try a Fox plug and lower nitro. I'll run a gallon of that through it and see if we can't tweek and improve. That is one down and one to go. At least I have somthing to go on with the other since it was acting the same
