Re: Chrysler Mods
It's that sense of deja vu, all over again.
'73 70hp in the family since new. Ignition unit died in '75. As the dizzy was a points unit he simply replaced the module with a coil, ballast resistor and conventional plugs. This ran faultlessly until I stopped using the base unleaded when Ethanol started to creep in to it. I found the points system just didn't have enough grunt to perform on 95 or 98 and the plugs fouled quite quickly.
I went back to the module system and converted to a hall-effect dizzy too. All a simple swap. But I do carry the points dizzy, coil and parts with me on board "just in case" I need them on the water one day. I can link'n'sync well enough on the water to get me home. Haven't needed to in the 4 years since I did the change, though.
However, I have since bought half a dozen motors from ebay for parts and play toys, so I carry a module with me now too. For the cost of a whole motors for parts versus a module from the wreckers, it's worth it. If you're space-challenged, strip the spares motor down and take the rest to Simms for the scrap value.
Valiant car modules aren't viable, nor worth the effort if they were. (Strangely, I own a Valiant too. It's not consciously a Chrysler thing, I think) I am actually trying one of these now:
High Energy Ignition Kit - Jaycar Electronics
With a Bosch HEC715 coil, I get about 40kV output which is getting into the range to properly fire 98 petrol on the surface gap plugs.
And incidentally, I find the Shell 98 to be by far the smoothest of all, testing tanks of Shell, BP, Caltex and Mobil back-to-back. 95's OK, but 98 is smoother, especially at idle and leaves the plugs cleaner. Some say it's money wasted but apples for apples I personally can reconcile the extra cost in smoothness, clean plugs and fuel system and although it's just an opinion, I reckon I use less of it too. Not that these motors can ever be considered economical!
