Hi guys! Latest update on trying to find a vacuum leak. I made a smoke machine. This is what I came up with. I taped the center carburetor off, So no smoke would escape. I connected the smoke machine to the port on my manifold. I found smoke coming out of the center carburetor top hat. That's a hole where the accelerator pump lives.I also found smoke coming out of the front carburetor there's a vent tube in it . Found no smoke either on front or back throttle plates. So what's everyone's thought on this? Remember I'm trying to run down a vacuum leak..
Thanks
