Hi Everyone,
I recently got a used Quadrajet carb from a guy.When I put it on
my engine,gas is leaking badly all round it.Is this from a stuck float or
something?

It could be. You put it on an already-carbureted car?

Re: Quadrajet 850 leaking gas around carb
is it leaking from the bottom around? did you put a gasket under it, and if so, what kind of shape is the gasket in? could just be that. does the car have problems starting or does it just leak gas

Re: Quadrajet 850 leaking gas around carb
What fuel pump are you using? Fuel pressure? Have you checked the float level?

Re: Quadrajet 850 leaking gas around carb
sounds like the usual quadrajet problem, gaskets have been ruined from sitting to long. the rebuild kits are cheap and the instructions are decent to follow for even a novice.

Re: Quadrajet 850 leaking gas around carb
You still haven't said if the car was originally carbed or not. This matters because of the fuel pressure.
