tuning help fouling plugs
I have a 1970 350 Pontiac believe it has been rebuilt before I got it and maybe a small "RV" cam. It has a 1405 eddy sitting on top of a single plane tomahawk intake. MSD ignition and distributor running no vacuum advance w/12 degrees timing at idle 23 at 2300 RPM, anymore and I would have a hot start/overworked starter problem.
My issue is I re jetted the carb due to an off idle stumble to a point of stalling sometimes, I could not tune out, the larger jets and rods fixed that. When I pulled a plug it was fouled some so my question is should I be worried about the fouled plugs? I don't have a heavy gas smell coming from the car when I drive it it idles at about 700 rpm 850ish in park.
as it sits now
Main jet .101
Rods are .073 x .042
with the pink step up springs (car has 15-16Hg)
What jet/rod combos have worked for anyone running a stockish 350 ?
After more reading around I am thinking it might be my choke as it wont adjust where I need it and gives me hard cold starts second opinions are welcomed
