for propane than

The only diffence is spark plug gap .34 instead of .45 or .60

propane needs a hotter spark other than that it,s the same. Hope

that helps you TJ

I would adjust the timing for best performance without more than

a bit of knock under maximum load. I recall that with propand you

can run LOTS more compression.
