I wonder if anybody can help me, please. I have a CAV GT40 with a 348 Ford Boss engine with MSD ignition running on 48IDA Weber carbs and seem to have an intermittent problem which I beleive is in the ignition system. Sometimes the car will run fine (last time indicated 430 bhp on the dyno) but after putting it in the garage it will only run on about 4 cylinders! I have take a couple of the plugs out and tried to test the spark but it seems very weak and I think that throttle pumping on starting is causing some of the plugs to foul up with the weak spark unable to burn the fuel on some of the plugs
Any help or guidance much appreciated!
