Dauntae,

Thanks a million -- sounds like good method. I'm a newbie who is getting his first instruction session this Sunday, but I have been playing with my Tower .46 in my trainer, because I feel that being competent in starting the engine and tuning it is as important as the flying side of things. I have gotten the top end all tuned out to the point of being lean when tilted upward, and then richened it back up a tad. I can get it to idle down super low without the glowplug, but open up the throttle to WOT, and it hesitates through the midrange and takes about 5-7 seconds to finally hit max RPM. Once I have it at max, I can back down to half throttle or 3/4 and then back to full without the hesitation. It only hesitates after its sat at idle for a few seconds.

From your instruction above it sounds that it's idling rich to me, am I following everything correctly?
