Re: 2 cycle 244cc timing marks?
My fuel pump had clear diaphragms which made it really hard to see a crack, but it was there. The buggy still ran, but ran poorly and smelled rich......
Keep in mind especially if you still have oil injection, when the lower diaphragm has a breach then unmixed fuel (from the tank) will get drawn directly into the crankcase resulting in a super lean mix. Oil injection happens after the carb on it's way to the crankcase, I was lucky as I premix mine.
