one way to tell if your idle is way too lean is, if you come off the throttle quickly to an idle, you may hear your engine make a sound "NAA NAA NAA NAA" and most likely your idle will be high and then it slowly come down to where it should be. and the sound will go away.
I have seen this many times in all kinds of 2st, from our glow engines to weed eaters, to motorcycles.

he still has not told us what prop is on the engine,. he said it was heavy... well heavy (and more pitch) is one thing, it loads an engine, but a longer prop produces more angular momentum
