Hello, I had a carb rebuilt (7042220) and I don’t have vacuum at any of the ports. The choke pull off does have vacuum there but I’m trying to get full manifold vacuum for my distributor vacuum advance. So I can’t adjust the idle mixture screws since my gauge doesn’t read anything. I’ve tried seeing if my gauge was malfunctioning but the ports are clearly not sucking when I uncap them. The gasket is on correctly but what seems to be the issue? Could they have been blocked during rebuild?
