Ignition Coil...
(Click here to view the original thread with full colors/images)

Took out my sons 50cc this weekend and after running fine two weekends ago - it won't start. The plug (grounded against the head) has a weak sporadic spark - maybe one small arc after a few seconds of cranking.
So I am thinking - test the coil. I have seen a couple of posts here indicating resistence numbers when testing an ignition coil - but non specific to a particular bike. Does anyone have the numbers for a Kasea 50, or does it matter that much? And while I'm at it - my neighbor has a spare from a redcat 70cc (four stroke) which looks completely different - can I assume that it is different (beyond the obvious cosmetics?). Or can it be fitted and used?

I see a ton of "fits all mini quad" coils on ebay.

Are all coils created equal?

You might just go through and do a thorough cleaning on all the connectors with some electrical contact cleaner. Also you might pull your flywheel and clean up everything as well.

Nope. Did all this. I am thinking of swapping in the igintion coil from my Polaris Sportsman 500 to rule out the coil. Anybody feel that this may damage something? ...or am I OK.
