The tach has started showing at idle and then a bit above, but then just doesn’t go any higher than about 1600 rpm. Is it a cable, magnetic reading, or? And what’s the best way to troubleshoot? I assume it won’t impact engine function if I don‘t over rev it, and sound is what I use mostly really operating now. Motor sounds fine.

Tips or hints?

And and overall tips or comments on that model?
