You shouldn’t really be getting any jingles, no matter how minor…Look for worn plug wires, coils, frayed primary leads, stop switch leads…
You could advertise on this site’s classifieds for those parts.
You could also look on ebay for a complete late model powerhead that is affordable. You would then just remove the pistons/rods from the ebay powerhead, and install them in yours…
