My flame arrestor needs cleani
My flame arrestor needs cleaning after every time out due to excessive oil buildup coming from breather tubes. If I put my thumb on either tube there is a pressure buildup. I assume this is blowby. Can this be caused by worn valve guides or is it only caused by piston ring blowby? There is a slight amount of smoke (from exhaust) when starting engine after sitting for days.
