got a 503 and it's not getting spark to one of the plugs, after testing ive found that it is infact metering out 4 times in one rev at the point's. would this be a points problem? when testing this one. and a test to the other cylinders spark and it wasn't working. but has been before hand.


Thanks anyone who might have some idea

last time I played with one for somebody with the same problem, it needed cleaning and gapping of the points and all was well. You get some odd readings with a meter because the magneto coil is grounded at alternate ends by both points, condensers and coils, with the black box thingy across there as well.


Hope you dont have to get at those parts, need small fingers....
