i got to agree with DaveG55 about how when its colder you richen your engine and when its hotter you lean it-i still dont understand how often i come across people posting the opposite

about getting a crisper take of and your engine dying after you let go its your lsn
sometimes people make the mistake of turning in the idle screw to keep the idle up
when your lsn is to rich your engine is real slugish and it will stall right after you let go of throttle
you then need to lean your lsn-try the pinch test it seems to work really well
