I just bought a sears 4hp motor today and the man i bought it from had problems not getting spark. He told me he didnt know much about boat motors.Now here is the problem... there is no spark the points are new but im not sure what the gap should be i think it is .018 but i think the main problem is in the wiring of the coil. There are 3 wires coming from the coil 1 goes to the plug 1 goes to the points and 1 goes to ground. is this correct? I am looking for a diagram but cant find one any help would be great. I would like to check this before changing the coil.
