I was given plug's that had been too long one engine ran fine the . . .well let's just say it closed the gap. . .
would start it use a rubber handled plier's and remove and reinstall each wire one at a time with it running if any wire or wire's that don't cause the miss to get worse are bad . . . I've new wire's that came faulty. . . anotherthing to try is start it and run it on the complete dark so you can see any arch's. . .
