HH100 Points ?

My 71 Custom XL with an HH100 points engine quit today. I just got it back together recently. I checked for spark and none. I had put new points and condenser in it but decided to pull the cover off any way and look at points. The points were stuck open cause the push rod wasn't going back in. I pushed it back in and spun the engine and they opened again but the rod didn't go back in. I tried to get the rod out and it was brittle and broke off flush. Now I guess I have to take the side cover off to get to it right ? Also, where can I get a new breaker push rod ?

Re: HH100 Points ?

Do you have a strong magnet? I wonder if that would pull it out. It's worth a try.

Re: HH100 Points ?

That's a common problem. They are made out of bakelite so a magnet isn't going to pull it.

The plunger isn't made anymore. A lot of folks have made replacement plungers out of brass stock. Do a google search for HH-100 Points Plunger and you will find any number of discussions.

Ya theres two parts to that system, the magnet and the points. if you know that the points are good, and you have no spark, check your mag

Take the small part that broke off and mic it.
Check the size and find a drill bit equal or smaller than the broken part.
Drill out whats left of the plunger and install a new one.
The fibered drilled out parts wont hurt your engine.

Kohler plunger is about twice the diameter of the Tecumseh one. Roger
