@RandyB the offer was serious and I was trying to steer you down the direction of rebuilding one so you have some knowledge of how carburetors work and why carburetors do what they do. It’s almost impossible to bolt one on out of the box, even brand new, and have it run flawlessly. Part of owning a carbureted engine is tuning, and fixing the carburetor on said engine. I put a brand new avs2 on a 347 sbf I built for a friend because he had to have it. Took me two weeks of spring, Rod and jet changes to get it right. It’s all just part of the territory. Learn to enjoy it.
