Hi all
After not starting my mc21 for over a year i fired it up only to find the upper cylinder not running at idle.it seems to run when a give it a few revs but runs cold on idle.i have cleaned the slow jet,the air screw and float valve,changed the spark plug,swapped the coils but nothing has worked.I have read on here that it could be the crank seals.So if that is the case i was wondering if anyone knows where in Australia i could get my crank rebuilt?
