Spark Plug - champion H8C - available at most auto parts stores - $4 or $5

Points - 29580-55 - these are hard to find. has them for $39.95

Condenser - 29578-55 - I don't know any source for these. These don't go bad often, when when they do, they can ruin your day. The one for the generator models 32726-47 should work, but it probably won't fit right. $5.95 same place.

??? Any other sources for points and condenser ???

I would buy a new spark plug, but clean up the points. Just take them out and carefully file them with a fine file. Try to get rid of the pits, but don't take off too much metal. And keep the surfaces square. Once you've got nice shiny surfaces, put them back in and see if you get spark.

You can test the condenser while you've got the points out. But be sure to zero the ohmmeter first - if it won't zero, the battery may be dead.

The spark on these is very hard to see. Close the garage door, turn out the lights, leave the spark plug out of the engine, kick it over and look for spark. A helper makes this job much easier.

If new plug and cleaning the points gets you spark, shell out the $$ for a new set of points.

Let us know how it works out.

It has been sitting for 20 years. I did have it running once but not very well.I replaced the tires and tried again but now no spark? I guess I'll get new points and condenser and plug. Is there a good place to get those parts?

Thanks for the info

Tell us about the condition of the bike. Has it been sitting for 20 years? Or have you had it running and suddenly it won't start? Have you redone the wiring, etc.

Start with a known good spark plug (Champion H8C), and gap it to .040 - .045.

Then clean and gap both sets of points to .018 The upper set of points runs the ignition while the lower set runs the stop light. The lower set is not critical, but they should be gapped correctly.

If the bike has been sitting awhile, you should remove the upper set, and dress them up with a points file.

The metal in the points does deteriorate - I used to have a 1960 Super 10 which I had to run a points file through the upper set almost every time I started it. Of course, a new set of points and condenser fixed that.


Does anyone have a way to diagnose a 1960 super 10 that does not have any spark?

Thanks Bryan
