I have a VLX-10S it is firing on clinders 1 and 3but no sparks on 2 and 4. It is getting fuel on 2 and 4 and compression Could it be the timing in it? The motor is running on 2 nad 4.
On that 1964 60hp Johnson, the only possible reason for no fire on 2 cylinders on one bank is either one set of points is faulty, one set of points set wrong, or the wire that connects the two set of points is missing.
