This is too weird. This engine will not start with factory settings. Primed, fueled, hot plug. It fires every flip and runs for one second. period. No GO. After a couple hours of that I started tweaking needles and found that backing the idle jet out permitted the engine to start and run at a fast idle. But then any advancement of throttle kills it. So, I tweak the same screw back in while engine is idling and low and behold the engine idles faster and I have full power using the throttle. Runs great, full power, but now I can't slow it down below about one third throttle which I doubt I could land the plane at. To sum it up, won't run unless idle screw is backed out a LOT, then runs only at idle. To get full power I again screw idle screw back in while at idle, but then I can't get it back to idle. High speed jet is set at factory setting which does seem correct.
I have repeated the above for two hours on three seperate days this month, same darn thing every time. Wish my Evolution was like everybody else's. HELP. Dan Cutter
