1600 fouling plugs

I have a modified 1600 with a weber 2bbl carb which keeps fouling plugs
when I Idle for more than a few minutes. Can anyone help me

Its jetted wrong, most likely.
Firstly try screwing in the idle mixture screw at the base of the carb, in
line with the car, a bit at a time. If you bottom out or are up to 1 1/2
turns from bottom out, then you need to rejet. Someone else will have a
better explanation.... I think you will need to reduce the primary idle jet.

Typical I dare say, for the centermounted weber progressive.. they run
so poorly in a bug because of that long intake manifold, that they have
to be jetter too rich to work. Switch to hotter plugs or replace the
carb with something else. Make sure you have good HEAT to the intake
manifold. You could try replacing the idle jets with smaller ones too.
(That really is the solution, but as a result you may have stalling
problems because of that carb/intake combination..)
