OK, another problem found with my carb. When I was checking the accelerator pump, I cant get air into the inlet side (or suck air out). I took it apart and everything looks fine. Even with everything removed from inside, I cant blow air through the inlet side. The outlet side (running to carbs) is clear. Looking at the body next to the inlet line, it looks like there might be some kind of check valve (ball bearing and spring maybe) in the base where the line comes in. Anyone familiar with that?
