1971 Rally 180, I had the motor out and everything looked good. I replaced the bearings and seals, but that was it.
It's all back together now, but I'm getting very weak spark and not sure why. The wiring was a bit dodgy when I got it, the previous owner had installed a kill switch that I removed. The rest of the wiring looks pretty good, so I used a diagram from scooterhelp and tried to put it all back to stock.
Tomorrow I'll check the timing, (no slot in the flywheel), would bad timing cause weak spark?

Spark plug, cap, wire, coil, stator - work backwards until you find problem.

Perhaps a long shot, but I had a hard time determining the + and - on the coil. Not sure if your Rally is similar to my VBB.

Tried a new plug, swapped out the coil, no spark at all now, so I replaced and gapped the points on the stator and I got spark!
