No spark

[Marqs1979]

I decided to order from Dragonfly and also a fitting EasyCAP from brightsparkmagnetos because I have so much custom fabrications already that I find it difficult to find enough time.
Thank you all !!

At last!! it has been on the wrong track !!! Yesterday it arrived from dragonfly :)
I was confused about the breakers.... is there no way to adjuste the breaker gap ???

[Triton Thrasher]

Of course the points are adjustable.

Is it a brass or steel backplate?

I do not understand where to set the breaker gap

[Triton Thrasher]

Fit the points to the magneto. Turn the engine until points are fully open. Check the gap.


if it's not 12 thou:-

Slightly loosen the centre screw, which holds the points into the armature's tapered socket.

Loosen that big screw which is visible in your photo. It goes through an oval hole in the bent plate that carries the "fixed" point. You can see the edge of that  hole in your photo.  Move the fixed point to correct the gap. It pivots about the centre.  Tighten the screws and check the gap again.

Thanks :-)

are those a new type reversable points?
I've never seen that type B4?

Give me the brass points any day. This is what happened to the steel backed ones in a Matchy twin.  http://i244.photobucket.com/albums/gg3/takka22/001_zpsa069537d.jpg

New in 1960.

This is what happened to the steel backed ones in a Matchy twin.

They are rather paltry.

I've had trouble with loose pivot posts.

really, it is a few years ago (mmm could be 8 /9) since I bought a set and thought they were something new then, but tempis fugit and all that

[Triton Thrasher]

I had never seen the tin points until I found you can't buy new brass plates, to replace worn ones. That was mid-1990s.

After 1959, there were fewer models with magnetos and the UK market collapsed anyway.

[bsa-bill]

you can't buy new brass plates,

yes, I have a brass set spare, changed it to steel ones when having starting problems with the RGF (higher compression), might have been a backward move as it didn't resolve the (no spark) starting problem, Pazon did so it is ignition, still have the magneto in bits, going to send it to one of our Maggie guys to get checked out (when I remember), it works on the Flash but not on the RGF (as does the one on the Flash if you see what I mean) so probably just needs to be better than good for HC

Hey!

Can someone explain how this part can be bent in this way? Do not understand what I did wrong ?? Is that the same thing has happened with Wilkos ??

I bent it back and then started the engine and went for a little while, then stopped and then became impossible to start. Then I checked the spark position and then it was all wrong again It must have changed What does that mean? Is it just to tighten the auto advance unit harder or may something else have happened?
