Is there anyone who can offer some help. I currently have no spark (you can see a very faint spark if it's very dark) done usual, check plug earths etc but nothing obvious. Took flywheel cover off and was full of white powder. Took off fly wheel and coils and surrounding area completely covered with like a chalky, lime covering. Thought found problem cleaned it all up put it back together had spark for 2 kicks but then back to no spark. Took flywheel back off and got coils out. The lighting coil seam to be about 8 ohms but the others wires to earth are about 1 meg. Does anyone know what the coil values should be? Have a wiring diagram for the ignition system or have any ideas of the problem. Also noted all paint has come off the inside caseing behind fly wheel and the casting in very poor or bits have broken off..

Not excesive play on the main bearings?

 

 

Is your pick up ok?

Bearings seem ok, How do I check pick up?

well first of all look for any damage. If the flywheel has some space because of bad bearings for example it could have hit. The stuff can also be residu of water evaporation or something.

Had a recent similar problem with a same year GG. The coils and pick up sensor all checked out ok with a resistance check, checked the earth connections, new HT coil, voltage reg and still a faint spark. Replaced the stator and that fixed the problem. Try swapping out the stator with a friends one to confirm the problem before buying.
