Try and search around the rest of the site to get familar with it

Cheers Phil

Has good spark nearly too good jump to earth 30mm away from motor

Well that is to good Any chance you have a actual spark tester? The kind with a resistor built in.

Im thinking the coil is colasping on it's self to early. Getting a kick back when try to start? or a back fire?

Had a real problem with mine when the stator/magnito when out and droped the charge early it would run eventualy.It didn't back fire but I had to kick the hell out of it to the point I'd be to tired to ride it. Might want to check the resitance of the charging coil I will look it up tommorow and get back to you Night time here eh.

Not sure why but it went out just after a re build OK couldn't leave you hanging

Charging coil #1 brown +

charging coil # 1 green -

100 ohm scale 640 to 960 ohms at 20 degres C temp

Coil # 2 pink +

coil #2 green - again 20c 100 ohms 464-696

Tested at the plug comming out of the mag

Pick up coil

red +

White -

100 ohms 248-372 ohms at 20 c

Hope this help check in tmorrow Ops try heating it up mine tested ok untill it got just over 20 c so I don't realy trust the book

Cheers Phil
