DOH! Ignition point system memory failure

<< < (3/7) > >>

ka-ja:
Stainless pan-head allen screws don't look too bad, and they tend not to chew up.

You could hammer the end into the screws and apply great force via the T handle. I had to drill the heads off 3 or four of the screws.

Palins, a blast from the past Ted. There was Bob Minions too. Still there last time I knew but Palins not the case. Also Samways, who again were still about but more bicycles stuff and smaller scooters? Samways for the highways was the slogan as I recall...

More local to me at the time in Duffield was Bill Lomas in Milford. Ex racer and his son Mick was no slouch on a bike.

I reversed the wires as K2 suggested and it ran perfectly.  I then switched the points cam around and put the wires back to normal.  One issue is that with the point plate at the correct 1-4 firing position, the 2-3 subplate has to be moved to it's absolute max (advance) position for the 2-3 timing to be correct and it's just barely able to achieve that.

I had the same issue Mike, ended up replacing the points. Quite sure it was due to the heel of the points being worn!

McCabe-Thiele (Ted):
Likewise, I suspect the problem is also more pronounced with none genuine points as well as heel wear.
I ended up changing my baseplate for my original 400 one as I fitted electronic ignition on the 400.

Once my 500 is run in I'm thinking of switching it to electronic.
