Evening all,

Just messing with the basic set up to get a nice idle (it has a splashy note to it), please note this is a Mk1V with a YC 1500 motor.

Started from basics but no better, (tappets, Compression 11.2 - 11.8 hot, dwell 40', dynamic ign 10') so probably carb related, but anyway I digress a little.

The dizzy is the original 1300 AC Delco unit, not overly worn as far as I know, but the point contacts are clean but do just not line up well, I also have noticeable timing scatter on the strobe. I seem to remember everyone poo-pooing this dizzy, so do I:

1 Leave it alone, it's working!
2 Replace the points with an electronic  pickup
3 Fit the proper Lucas unit (new dizzy & revcounter)
4 Go Lucas & electronic!
5 Even more expensive!!!!

Ignore, 5, it's a bit of a luxury.....

Hello Blubayou,

if it's only the idle you are concerned about and the car runs well, I'd leave it as it is. otherwise option three.

Remember about the law of diminishing returns.

Tune it by ear/feel.

Take the car for a drive, and advance the timing until the car starts to pink under load. Then retard just enough to stop the pinking. That is about as good as you will get it.

"I also have noticeable timing scatter on the strobe."

The Delco on my Spit was rather sloppy and gave this same problem so made an adapter to connect a flexible drive to the vernier adjuster and brought it through to under the dash on the drivers side so the timing could be adjusted on the road to get the optimal position.    Back to early 1900s technology, rolling car rather than rolling road.

Disconnected once set, but still in position for adjustment when required.

Thanks for the ideas guys. Just messing with the timing, found some interesting discrepancies. If I check the timing on number 4, it's a whole 4' behind number 1 consistently. Heaven knows what 2 & 3 are!

Based on this info I have timed it up at 12' on number one & it's all running well.

Have also ordered an 'Accuspark' unit as a cheap way of negating the crude points setup.

I'll update when fitted, be interesting to see if timing accuracy improves a little

That's probably quite a common feature Blubayou, but not many people actually look for it.

Evening all,

just fitted the 'Accuspark' unit, easy to fit, nice quality.

Timing scatter gone!  

Just thrashed it around with the timing set at 18' @ 1000rpm.

No audible pinking under load, drives very well, 0 - 60 in 12.5s (sat nav) so it's going well.

Still have slightly rough idle, will investigate another day.
