Re: #1 plug question
The gap between the rotor tip and the contact in the distributor cap has been advertised to be twenty five thousands . The gap should be the same at all four contacts in the distributor cap . More gap to a certain point can increase the intensity of the spark , less gap decreases the spark intensity . This is why that the gap needs to be the same on all four cylinders . I use a gap of thirty five thousands for hotter spark . This isn't a recommendation but just what I do for hotter spark at the spark plug . I also prefer the hotter Champion W-18 spark plugs .
