Avs2 650 tuning on a 340

I have tried a larger squirter but that did not help. Went to rich. Also have tried the stronger accelerator pump from the 800 carb. Right now with the top shot and .031 squirted it seems ok. I can see the rich blip on the af gauge.
I appreciate your reply. I will look into changing the distributor springs.


Lose the O2 for now and make it run. You are chasing a number that may not mean anything. Don’t be married to an O2 reading. Ever.
