Quick question.
I'm currently toying with the idea of going electronic on the DAF but I don't seem to be able to find anyone doing kits for 2 cylinder Bosch distributors.
Anyone know of a kit that might fit?

tbh, the ignition amplifier should be pretty much the same regardless of the engine - it's just the little bit that replaces the contacts that changes.
Should be easy enough to pick up a kit for a 4cyl engine, lop off two of the fins (or just make your own plate entirely?) and make a little mounting point for the optical pickup
May be the easiest option, bar getting a custom one made up specially by the company....

Well the original setup is pretty much the same base unit as a type 1 VW. Bar half the cylinders. Rotor arm, points and dizzy body are the same.
If only it was a 2cv which runs wasted spark.

In that case, slap in a kit meant for a type 1 vw! lol, if the dizzy cap just has a point either end, with blanks where the other 2 should normally be, I'd personally just leave it be, without any other mods

I'd go with your suggestion of disabling two of the sparks but you'd need a kit with an optical sensor to have fins you can chop off and AFAIK the cheap ones use a magnetic(?) doughnut thing to replace the cam instead. Or else you could replace the cap with a four lead one and just ground the two unused leads perhaps. Or, keep your points and fit one of these transistor amplifier kits. The idea is it stops the points getting pitted over time as there's no longer much current flowing though them, though it does nothing to stop the cam follower wearing. Maplins stock it I think. |

Using the 4-lead cap is a bloody good idea!  |

what does the dizzy look like? ive fitted a few lumention kits to vws, and id go with the suggestion of one of those with two fins lopped off as its uses a optical sensor. its what i thought of as soon as i saw the thread title anyway!
I'm not entirely sure why everyone has been bemoaning points on here recently though. ive had far, far more problems with electronic ign systems packing up than i ever have with points. pitted/burnt points are bodgeable to get you home, burnt out elec. igns. arent.
and a spare pair of points and a condensor in the glovebox is like £3 as opposed to £40+ for another elec. setup..........

As with points, I think it's the do with the quality more than anything. On the cheaper electronic kits the quality is variable as it is on cheaper points parts (which IMO are harder to source (Is Lucas/OE packaging enough these days bar maybe Bosch stuff?)). As for the OP I would be tempted to go with a Points assisted system or see if it shares its dizzy with other cars (2CV or Fiat 500 maybe?) and see if that system will fit (123 do distributors for the above with variable curves etc.). |

The problem is not so much with the points but shaft wear as the timing doesn't stay set right for more than a couple of hundred miles. Its go electronic or dizzy rebuild time |

Rebuild the dizzy IMO or source a good replacement (maybe H&H ignitions can help). If your shaft is worn, the bearings and spring weights may not also be in the best of shap either.

Otherwise a kit for a BMW boxer. Better, put the whole BMW engine in it! |

There was a generic aftermarket electronic kit for them too - Boyer Bransden I think? One of them and a twin lead bike coil might work quite nicely, once the distributor is fixed. |
