In respect to this, how do you fix a fouled spark plug?
My RX7 was fouling plugs for a long time while we were getting the mixture settings right. Use a small bit of wire to pull any solids out of the gap, and spray the inside with carb cleaner. Wipe it down and let it dry off a bit. Then go and get a windproof lighter or a butane torch, and force the flame into the gap.
What is the correct spark plug gap?
Also, the spark plug gap should never exceed . 055″ unless pre-set by the manufacturer. Spark plug gap is where spark plug spark discharge is designed to take place. On a conventional spark plug, it is the area between the center and the ground electrode.
