Avs2 650 tuning on a 340

That is in Alignment for most on the timing! You have that part nailed!

You seem to be chasing a CFM issue. Any chance you have a friend nearby with an 800AVS2?

I assume the total timing no vacuum advance and blocked is 35 degrees at preferably 2k RPM.

I do not know anyone else with a carb that I can borrow. Yes I know thet would be a great way to test out stuff. No vaccum advance. Total right now is 32. I have been trying between 32 and 38 total. Total comes in around 2800 I believe. I wouldn't think a 650 is to small. Based on the carb calculator a 600 is all I would need. Plus at wide open throttle the air fuel is good. But I'm still learning could be wrong
