anyone have any tips on how to line up the case so the cylinder meets it flush? should I be putting any sealant between the two cases where they meet? if anyone has anything else to add on how to rebuild it it would be much appreciate. thanks
A steel ruler can be used as a straight edge to line up the barrel mating surface on the crankcase then tighten the crankcase
bolts.
I use the non hardening Aviation Gasket Sealant between the crank cases if they are straight if not you would
need to sand them flat but very rare for them to need sanding.
I know some people don't use anything between the 2 crankcases on a mower but I just do the same as a bike motor
and use the Aviation Gasket Sealant and haven't had a problem but lots of other products could be used.
