HI I AM NEW TO GAS ENGINES WAS WONDERING HOW THE GAP ON THE COIL IS SET ? IS THERE A GUAGE OF SOME SORT?AND WILL PAINTING THE FINS PREVENT PROPER COOLING? THANK YOU

Coil gap is .010 .A calling card works fine. Fins can be painted. Use automotive high temp. paint . Just light coats.

Coil clearance isnt critical......most advice says use a dollar bill folded once,a business card,or a .010 feeler gauge.
I suppose I wouldnt argue with any purist who says paint on the fins would affect their ability to radiate heat to some extent.I have painted a couple of my engines with hi temp engine block paint (Cummins Diesel Green!) with no noticable affect although I didnt use a temp probe before and after.....

I set coil gaps at .010", using feeler gauges. I paint fins and mufflers with Rustoleum - high temp. flat black spray paint made especially for gas grills. Works great.
