Outer Limits 4x4 Board

Hi all,

I have a follow up on my manifold sealing problem.

I finally got the manifold to seal by making extra thick gaskets from exhaust manifold gasket material.

Problem is the car still won't run.

I had issues with the quady that I replaced the Holley with, so I sent it away and had it reconditioned. Got it back and it was no better. I took the car back to the carby guy and he found all sorts of vacuum leaks and faulty pipes and he reset the timing, 1 big vacuum leak was stopping it from idling but now it still won't rev as soon as you try to take off quick it has a massive flat spot and the motor just dies until you back off again. if you ease it away it will slowly accelerate but at a pace that is not drivable. The carby guy didn't like the manifold saying that it would never be very efficient but I don't think that can account for the problems I'm having.

Any ideas I'm desperate. (I've had to take the jeep out driving)

Thanks Glen

Sounds like the accelerator pump is not working as it should. can you see it squirt 2 jets of fuel into the caby when you move the accelarator linkages?

Seems to be working. When I work the linkages there is 1 squirt in either side.

I'm thinking I will have to try and find another quady to try and see if it's the carby or something else.

The carby guy assures me it's not the carby but doesn't know what it is

But I figure that it must be because all I've changed is the carby and manifold.

Anyone have a quady they can lend me for an hour

Sorry I don't have one anymore. When I had a v8 in my rangie, I use a quadrajet from a holden v8 and had no trouble with it. Only thing I changed on the carbie was to fit an electric choke.

I had this problem with a 2 barrel holley on a P76 motor. I read the holley book (came with the car), and its a classic symptom of fuel level too low in the carbie. Easy to fix on a holley - don't know about on a quadreject. The lower the fuel level is, the worse it does it.

Hi Guys,

Thanks for the help

I borrowed a 4brl Holley and replaced the Quady with that. Guess what, same problem

I can only figure now that it may be related to the manifold?

This weekend I'll be taking that off and checking the seals.

Any thoughts let me know
