Accelerator Pump rod linkage placement

[bob_lafrentz]

Hi all,

I have a 69 stock 302 carbed motor. I am rebuilding the carb. The question I have is which hole should I put the linkage in? There are four choices. And, just out of curosity, what exactly does this adjustment do?

Also, does gasoline break down teflon tape?

Thanks.

The pump lever (sticks across the accelerator pump in the front
of the carb) has two holes, inboard and outboard. The outboard
hole is the one closest to the tip of the lever.

The throttle lever has four holes, A, B, C, D, in order. The hole D
is at the top.

Choosing the inboard hole on the pump lever gives you a bigger
accelerator pump squirt and choosing outboard hole gives you a
smaller squirt.

Choosing the top hole (D) on the throttle lever gives you a bigger
accelerator pump squirt, and choosing (A) gives you a smaller squirt.

You can choose various combinations to tune the size of your
accelerator pump squirt (try hole B in hot weather or at high
altitude, try D in cold weather).

The instructions that came with my 2100 rebuild kit say that for
a 1969 truck with a 302, use the inboard hole on the pump lever
and the second hole from the top (C) on the throttle lever.
