Don’t know. I just picked it up last week. I tested the spark and got strong spark on one lead and weaker spark on the other. The leads were very corroded so I’ll change them. Of course, opening of the points is not an instantaneous event – it follows the outline of the cam. The question is whether the timing could be thrown off enough to affect performance. My guess is that it would not, but I’m not sure.
Actually, it is an instantaneous event—within reason, of course. The points are supposed to just barely break contact at a certain time as the flywheel magnets pass by the coil laminated core. Yeah, thanks to OMC’s reliability, it will run to some degree, even if it is out of spec—but how far out of spec and how well it runs is the question.
