I'm about there I'd say. I had the gauge in my hand while I was turning the idle screw, like you said too far in and it would start to falter and the vac would start dropping. If I was fast enough, I could keep it running by backing the screw out. I just turned to the spot that looked the best on the gauge and ran well.

Not sure what that part is. Do you have to take the bowl off to check that?

Just went outside to see if I made a difference earlier today. After 2 attempts she fired up and idled well. I didn't have to choke it for it to run so I guess I didn't something right.

Lol I think I'm in over my head, but I'm trying.

Thanks again
