Air gap between coil module and flywheel should be .010 inches.
1982 318 pick up coil gap
0.010-0.014"
0.010-0.014" is the Briggs spec
.010 to .012"
Tecumseh provides dealers with a 0.012" air gap guage, but 0.010 - 0.014" will do.
The proper air gap clearance for that model is 0.020"
The gap should be about .0125 in. (.3175 mm.) or the thickness of heavy paper.
I fixed the problem it was the air gap.
I think what you are wanting is the air gap between the flywheel and the coil . The gap is somewhere around .002 in , but if you will take 2 matchbooks take off the covers and use them for spacers between the coil legs and the flywheel . Role the flywheel around till the magnet pulls the coil in . Place the matchbooks between the coil arms and the flywheel and tighten the screws . Check the spark plug and make sure you have good fire .
you can go to any parts store and buy a feeler gauge for a couple of dollars. use that to set the air gap between the coil and the flywheel. use the oem specs
The gap should be between .006 and .010 if it has aluminum clylinders. The gap should be between .010 and .014 if it has cast iron cylinders.
