How to set contact breaker points

This video explains how to repair points on pretty much any motor. It goes into more detail about setting them on a Z50R but the cleaning process is universal for all points. Source: TheAlexManVideos on YouTube

I got mine from Wickes, £40, but its damned useful for lots of things including getting engine screws out where a screwdriver would fail. Well worth the investment!


That's not too bad! I'll have a look what can be bought here!

As I understand the spark timing is set with the breaker gap i e. The points cannot move in respect to the cam. So once the timing is correct the gap should be correct and vice versa. In the older cars you could rotate the breaker points baseplate to set timing and adjust the gap separately


The spark timing is partially set with the gap indeed. The cam is always in a fixed position. (forget about advancing for now).

So there is a T and an F on the flywheel. You need T(op) for adjusting your valve rocker clearance and at F(ire) your points should open. This is the default setting. From that point you can experiment with letting it open a smidge later or sooner.

Regarding the baseplate, I can remember this from my Puch moped that I drove when I was young. Was handy to have, but also a real pain to adjust.

An impact driver with socket will undo that flywheen nut easily without having to lock it.


Very true, however not everyone has such a tool, me included.
