Problem: 69' auto. Newly rebuilt 350 ran fine first 500 mi, then all of a sudden at start-up, it fouled the plugs.
History: 350, .030 over, 10:1 flat tops, high lift cam, 2.02/64cc heads, roller rockers, Performer RPM intake, 670cfm Street Avenger, Accel points dist., Mallory coil, Autolite #26 plugs, Holley mech fuel pump. All components brand new.
What I've checked: Firing order, dist cap, points, for vacuum leaks, valve adjustment, choke, floats, jets, power valve.
What I don't understand is I put new plugs in, stepped up the heat range, and didn't make a difference at all. I suspect fuel related but I am baffled. Suggestions?

It is fuel fouling the plugs right?? not oil fouling them.

Reading this again, I would look at the power valve and float settings again.

Also, I personally had no luck with autolite plugs in anything!! Even my weedeater chugs on these...

Lost 12 Volts (or ground) for the Choke heater?

Is choke working correctly?
