The mag on my 57 dominator 88 has a poor spark on one cylinder pobably because the contact breaker gap cannot be set the same and so the energy transfer will ok on one pot but not the other. The ring cam measures the same thickness on both lobes. Any Ideas why the gaps are different please. Unfortunately, I've damaged the armature getting it out. Anybody got any knowledge of replacement parts or repair shop that can refurbish magnetos.

Many thanks

Hi Jon

My point of view on magneto repair etcis that it is ablack art but I'm a retired Mech Eng and this eletrickery stuff is magic to me.

Seriously you could try Brightsparks or Armoto both web addresses below. Neither company is exactly cheap but what is these days.

hello well you come to the right place I rebuilt many Lucas mags k2f and k2fc there is two screws on the under side and the earth brush to remove and you can undo the point set by the center small bolt the cam plate as a locking peg on one side and most be fitted in the right up your drive side cylinder the left hand one fires first the nearness plug lead to the engine is for the right hand cylinder it fires last you now need to test your field by wrapping a length of copper wire round the armature to earth end of the armature and with a multimeter see if you have a reading if you get something around 9v then there a chance the armature maybe ok but I known someone in this business will jump in with both feet, were as i just try help yours anna j
