 Topic: WD electronic ignition
Posted: 28 Nov 2023 at 7:13pm |
|
Has anyone put electronic ignition on a WD with a WICO XB-4000 distributor? Pertronix said they don't have an application for this distributor. Is there another company that does?

I dont know if there is something "ODD" about the 4000 model or not.. But the do make one for a WICO distributor... maybe send a photo of your inards and the shaft diameter and see if they have something "CLOSE" that you could do.....
If they are interested, you MIGHT be able to make a deal with their Engineering Dept to send them your distributor and let THEM see what would fit..... Then you BOTH win ?

The reason you can't find an electronic ignition kit for a Wico XB-4000 Distributor, is because the Wico XB-4000 is a MAGNETO.
You can find the entire manual here:
The Spec XB-4000 is a clockwise rotation 30 degree advance unit, with a condenser capacity between .30 and .34 Mfd.
The Wico XB-series is actually a bit rare in the Allis realm, MOST of the time, you'll find Bosch-style magnetos either made by Allis, American Bosch, or Fairbanks Morse. The XB had a centrifugal advance, while Bosch-pattern units used an impulse coupling, and this coupling put the Wico XB at a disadvantage when hand-starting, so the XB's were usually put on machines that were fitted with electric start from the factory.
I have two generators that are exciter-cranked were fitted the Wico XB specifically for that reason... they were never intended to be regularly hand-started.
If you're trying to affect a restoration, and your WD came originally with the XB, take it to a magneto guy and have it refurbished. If authenticity isn't a concern, and you want electronic ignition, get a distributor drive system and a Delco distributor from a donor tractor, have the Delco gone through (the distributor shaft bushing, especially) and use the common-and-popular Pertronix kit... but don't discard the XB.

Not that hard to convert to a Delco distributor setup. Parts readily available.

By the way, Gene-
You're missing a string:
But don't fret it:
Just try to stay out of treble.
