Re: Johnson 5hp points
.020" But first take them apart and clean each contact individually. Do one set at a time so you have a sample to aid in reassembly. Watch all those little insulators and don't lose anything. Clean everything with electrical cleaner spray from the auto parts store. Clean the contacts with some 400 grit wet-or-dry sandpaper. Try to keep them flat, but you won't succeed. The result will be slightly convex surfaces. That's great and just what you want. The push rod goes with the rounded end against the point arm, not what you would expect.
