Good, informative topic. I think I'll go check my regulator.

What about the regulator/rectifier?

Thanks. Will check out countrycat!

The play on my KQ 300 (1998) choke doesn't allow for the full movement downward on the thumb lever. So it goes about halfway down and if I push a little too far the cable pops out of the plastic setting it sits inside of. Then of course I have to take the control unit apart and put it back into position. Is it normal for the thumb lever to not go all the way down? I have no play left in the adjustment screw on the cable in the correct direction. The only play I have left would make it worse. It'a a new-to-me quad so I'm not sure if it's a replacement cable or OEM. Thanks

Would really appreciate a live link for a 1998 King Quad 300 service manual. Cheers

Yep. Or the notoriously bad petcock. Anyway, it appears there are multiple topics going on here. 😀

Did you check all your electrical contacts from battery terminals to starter? I did that with mine as well as taking the starter apart and cleaning it well. Works like a champ now.
