welcome Beechtech!!!
i have a 100 and its a great engine, the more fuel you run through it the smoother it will idle and run.
how much fuel have you run through it so far? if more than a gallon you can lean her on down, i have mine at 1/2 turn out on the idle and just shy of 2 out on the high speed, youll love it once you get her tuned in, let me know how it goes, and there are a bunch of great and knowledgeble guys here so any more Q's just let us know

good luck
