Hello Ken.
It could be a number of things. Condenser, coil or just dirty points.
Start at the basics by cleaning and adjust points. 12 tho isn't it?

Do you have a reasonably good multimeter? If so measure the HT side of the coil. That's from a good grounding to where the spark comes out of the coil. Take the cap off first.

Cheers Scott


I set my RS1 points to 0.015" on the Buzacott but cleaning and gapping is very inportant. If you have a multi-meter also test continuity of the HT lead from the contact inside the cap to the connector on the end of the lead. with condensors I think a Holden style one from Bosch a GL106I think will work inside or better still a film capacitor from the local electronic shop / jaycar. After these simple items then its time to test the coil as Scotty suggests.
