Check the shoulder on the offending sprocket and compare it to the stock one or another known good one (one that didnt rub , no matter the tooth count).. It seems that I remember someone else finding that there was less of a shoulder on some of the aftermarket sprockets.This moved the sprocket/chain closer to the case and the chain actually rubbed on it (the crankcase).

PS I wore out a few 13th sprockets on mine with no issues. MOOSE brand FWIW
