My 315 poly keeps running after everything turned off..

I have redone all ground cables. Carb rebuilt by professionals. Pertronix electronic ignition in distributor, wired correctly. No more resistor on top of coil, need 12 volts for electronic ignition. New solenoid on fender for starter. New ignition on dash. New electronic fuel pump wired to acc on ignition. Fuel regulator before carb. I did see some light or spark coming from generator while running. All wiring done according to wiring diagram in shop manual. The idle on carb (stromberg ww) is done with adjusting screw.
Manual choke also.
"New electronic fuel pump wired to acc on ignition." THERE is your problem. You need to isolate the fuel pump power from the ignition.
