Thread: still fouling plugs

Tweet

I have the mechanical secondary carb.The plugs clean up after a pass or two but when idling around the house they blacking up and start to foul.I have 80 to 85psi of oil pressure when cold but with the carb running rich I have to idle it up some so the pressure climbs to 90 or better untill it gets warm then it settles down to about 40psi for normal oparating temp at idle.It does smoke a little just when i first crank it up and it does seem like oil smoke (white) not black from fuel.Thats whats so strange it fouls plugs but I have never seen black smoke out the exhaust from excessive fuel.
I made seven passes at the track two weeks ago and it never smoked while making a pass.So could oil be fouling the plugs?When I ran the cranking compression they were all around 185psi but that was a while back i havent checked it in awhile.And I have been running pump gas so far.This is a street legal car but I plan on doing some bracket racing with it mostly not to much street driving.
THANKS TO EVERYONE FOR THE HELP AND I WISH ALL A SAFE AND HAPPY THANKSGIVING.
