[QUOTE="Jim Bush, post: 176031, member: 3807"] Yes looks like it - the spring needs to be adjusted to clear the cam-ring - use the screw on the brass pillar. The points plate has to be removed - unscrew the centre screw and before pulling it out give it light tap to release the taper. It goes back in located by a tag. Points gap also looks big - should be 12thou. The plastic nub is an insulator, the spring arm needs to not contact the points block. The easy cap is the easiest solution for a mag with these symptoms. The mag can be removed without removing the timing cover - only the inspection plate to loosen the auto advance, and the three nuts/1 long stud nut to remove the mag. Disassembly of the mag is easy - lots of details on line. Don't forget to remove the 2 arcing screws and the pickups, otherwise will damage the Bakelite slip ring when you pull the armature out. Brightspark provide excellent instructions with photos for the condensorectomy - essentially unsoldering two wires from the existing capacitor and covering them with shrink tube. Can be done in 1/2 hour if you don't have to rectify any other issues with the mag. It will get you back running reliably for a while. Its a good idea to replace bearing oil seal and clean lube the bearings and replace all carbon brushes (3 No.), clean adjust the points. The mag has to be re-timed when you re-install it - lots of information on that. [/QUOTE]
