I understand the fuel, spark, compression concept, but you have to admit that it's a lot easier to sort out with a 60s carbureted motor.

Anyway, I switched the plugs between cylinders 4 and 5 and there was no change. They both looked fine (not fouled).

I guess the next step is to start looking at the fuel supply.

Thanks for the help!!
