Auto advance stuck and mag has issues

[BSA500]

No wiggle on the armature that I can detect. It was rebuilt as recently as April and I am sending back to let the well renowned Andrew at Priory magneto's to cast his expert eye over. He is very good he has done a few rebuilds on dynamo's for me to a very high level.

Problem solved then. Good plan! Summat funny must have happened then, as it certainly wouldn't have been like that when Andrew had done with it.

I know but recently I have had the DVR2 regulator fail,perhaps I am waiting to hear, they never fail. Since I rebuilt the engine/dynamo/magneto and carb I have never had some many issues. It was more reliable when it consumed more oil than petrol.

Magneto is repaired and on its way back. Andrew said the play wasn't too disastrous back the probelm starting was because the points had shut closed??. Never touched them so how?. Also some tracking along the slip ring. So he has worked his magic and has sent it back to me.

Points gaps have to be checked and adusted.

It's maintenance.

The mag had only been on the bike for a month or so and only 200 miles done. In the 27 years I have owned this bike it was generally a once a year job and even then they hadn't changed. So wasn't really looking to that as the reason behind the bikes difficult starting.

If they are new points then they settle down and bed in

Next time a bike won't start, check plugs first, then points.

I notice you checked timing in Post #1. That would have been a godd time to check the gap.

Not trying to annoy you.  Bet it won't catch you out again.

Yeah did all the usual checks and at first no spark, then they returned rinse and repeat. Andrew did say there were a few issues so he replaced the slip ring/armature and pick up brushes just to be sure. He does a very good job. I was mislead into thinking it was fuel first off as the mag was only a couple of months post rebuild. We all miss the obvious if we don't look . I got led off piste with the points when I noticed the armature play and of course fixated on it

[BSA500]

Mag back in starts first kick and ticks over as it should. There was a horrible noise first start, turned out the fibre gear was too tight  to the cam gear, a quick mounting bolt wiggle sorted that. Andrew did another great job with his skills etc around mags and also dynamo's.

Thanks for your kind remarks.
