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 ????
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.
