its probly not just something it could be theres alot of areas on a two stroke to cause problems with idle speed and running lean and once i check the carb is not the problem on my bike its usualy air leaking through a crank seal, crack in a case, worn rubbers, holes in the exhaust, ignition timing, rust in the cables, frayed cables, oil pump cable sticking ..................
