feetupfun Posted December 7, 2010 Report Share Posted December 7, 2010 There are lots of possible causes for a poor spark not just a poor HT coil earth. also consider: Poor stator coil earth Capacitor condition Stator to magnets clearance Stator plate rotated away from ideal position Points dirty/wrong gap Poor connections in wiring Poor earth from motor to frame Leakage to earth via kill switch or points wiring MK8 Pursang front wheel should fit in the front end of a M199A. May need work on axle length, axle spacer and brake stay arm. Quote Link to comment Share on other sites More sharing options...
