Spark Plug

Post by BrianDowning »

My Model 8 was converted to 12V some time before I bought it. The plug is an N-5 (Champion) and seems in good condition. Anyone know what the proper gap should be?

'62 with coil ignition? I'd say 22-25 thou. Personally I've found 25 is a good gap on most coil ignition machines.
Shouldn't make any odds that it's been converted to 12v - presumably it is a 12v coil though!?
