So I am getting acceleration lag on my setup? When I put my foot to the floor I have to wait a couple of seconds for acceleration to kick in. To much fuel or to little, not enough advanced or maybe accelerator pump problems.
What I have is (2)Weber 32/36's with 140 jets in the primarys and secondarys. Chokes are removed. Webers are mounted to a draw though Eaton M62 Supercharger.
I did order a pair of dual accelerator pump jets (stock Weber's come with a single accelerator pump jet). Thought maybe not enough fuel. Wont know if this is my problem until I get them and haven't done any full thottle tests on spark plugs. Replacing rear brake shoes so car is back up on jacks.
Could be a whole lot of different things - who knows.
Lend me your comments.

Hey Ernie, what about fuel flow - i.e. big enough pump or line? Is it starving for fuel?

Oh. Upgraded fuel line to 5/16 and electric fuel pump in the rear that flows more than enough fuel at around 4-6 psi.
Thanks Evan!

Well in my setup that I had I just ran standed 125 primary 140 secondary jets on a 32/36 and got good response, you are trying to tune it off of the ground are u if so that won't work very well as things opperate differant under load I didn't really have problems with my carbi my problems was more to do with timing and the amount of boost I was running! What sort of dizzy and what boost u running??

I had the car out on the road the other day before I started working on the rear brakes so I had a chance to drive it under load. My timing is set at 10 over advanced with stock dizzy for Z24. Not sure how far it is advancing under load. Boost is topping out around 8psi. Let me know if more if is needed. Thanks.
