Gotta hate that cobbled togethor stuff.
I’d bite the bullet and rebuild one of the others with a much better kit from Cliff Ruggles.

Got a hold of Cliff, Short conversation and he steered me exactly where I needed to go, Great guy.

Basic rebuild kit was purchased, used the 72 Dated Q-Jet that was organic to my Burb and runs great. No more re manufactured crap.

They aren’t all crap.
Sean builds nice carbs.

Good to see you got it fixed up.

Re: Help...1972 350 W/HEI

If you still have the stock exhaust, make sure the riser valve(if it is still there) is working. I learned the hard way many years ago that too much heat on a Q-jet can screw it up, causing severe flooding. In my case, it was a collapsed inner wall on the OEM double wall Y-pipe blocking off one side that caused the problem.

If it is too late to return your newer troublesome Q-jet, worse case, you have a nice source of spare parts for future repairs.
