I have had an Accuspark DK4A fitted fitted to my Austin Seven for a few years, It did not work day 1, being a retired electronics engineer I figured it was more to do with my car than the unit. I found it was very sensitive to electrical noise so I installed a special filter and all was fine till I upgraded my engine and it now revs in excess of 5000rpm. What I found was the engine started to misfire as the temperature came up above (70deg on hills). I had no idea what it was and tended to live with the problem till it revealed itself. Recently I went on holiday in the Highlands and decided to climb Glenelg and take the ferry to Skye. The engine failed completely and was traced to the Hall Effect sensor at the side of the road, it just died.

After getting towed back I contacted Accuspark and initially they wanted £44.95 for Kit 39, reducing it to £20 with proof of purchase of the original distributor. I was not keen to fit the same part again as I suspected there is an issue with that part.

However I found a part ETC5835K costing £18.66 + VAT and postage that looked exactly similar. Here is a video of my failure and any comment would be welcome.

I can't specifically comment on that, but i'm planning on upgrading the distributor on my Supercharged MGB - Locost using a 123 Tune+ distributor, which gives the ability to programme advance curves via bluetooth on an iOS device. Not cheap, but drops straight in with just a 12v connection to add....

Sounds like a plan, I wonder if the Lucas version would/ could be made to fit my Austin

I have just checked and apart from the gear on the end (which I have a spare one) it might actually fit, thanks for the tip, I will have to save up my pocket money now.

As an alternative, I have used pertronix (usually rehashed Aldon) for many years. More expensive than the crappy accuspark. Much cheaper than 123. The one in my vitesse did me 13years. After I sold the dizzy it is still running fine.
Bought from retrorockets. Pay in dollars, ships from Surrey.
