M38A1 Solid state ignition conversion

[MikeM38A1]

Hi Guys,

I read with interest the article and video on the M38A1 conversion to solid state ignition using a Swiss unit, designed for the M151.
From my 2007 restoration, to date I have gone through a handful of condensers from unknown origins, and decided to convert.

One of our UK suppliers now imports the unit at £50 per unit.
It was a straight forward conversion and once the new locating notch is made in the dizzy housing, I set the timing at dead on 5 deg, btdc, and plug gaps at 25 thou. and it fired up instantly and ran smoother.

My question is, should the plug gaps be opened to 32--36 thou, as on the Mutt, and or advance the timing ????

Any advice appreciated, as usual,

Thanks,

Mike.

Yes and no one actually sells a conversion. You simply buy the M151 Swiss igntion unit and modify it to fit your M38 or M38A1 distributor. This is an old topic and if you search a bit you'll find the background on it. Also visit my photo album's sub-album on ignition systems.

This is the late 151 Swiss system referred to above.


This is the early 151 Prestolite system and the one I prefer but it is much harder to find.


Here they are side by side.

Erik Maes did the conversion mentioned above and has documented it quite well several years ago.

Here is where it all started in 2006:
