What should the piston ring gap be for ring 1 and 2 for 0.040 oversize piston on a 1982 2F motor?

Does this sound correct: MINIMUM of .0035 gap per inch of cylinder diameter. Example: 4″ (bore) x .0035 = .0 14 minimum gap.

The FSM doesn’t mention different size pistons. #1 = 0.20 - 0.56mm or 0.0079 - 0.0220in
#2 = 0.20 - 0.58mm or 0.0079 - 0.0228in

There is a calculation for ring gap based on piston diameter. Sould be available on the net somewhere. Remember to gap the oil control rings too.

Thank you. I found this calculator.

RING END GAP CALCULATOR

Too little ring end gap can result in catastrophic engine damage! Always inspect ring end gap during the assembly process and correct this before final assembly! As a general guideline, ring end gap that is larger than expected is less of an operational concern than too little end gap...
