I used to believe that same story and repeated it often." Give me a pliars, screwdriver and pocket knife and I can fix a point ignition system and get home." I repeated that until a smart fellow said,"Yeah, lets see you fix a shorted / open coil or condenser with your Knife, screwdriver, pliars." I had to admit, I could no more "fix" a failed coil or condenser than an electronic ignition module, so I don't say that anymore. ;-).
I will say that I have yet to see a point system converted to solid state electronic that does not start better and run smoother, pull better.
Points are so dependant on the cam lobes and distributor shafts and bushing having little wear so point gap / dwell stays constant, so ignition timing is spot on for all cylinders. Maybe a lot of the improvment is because the electronic conversion is usually installed in a well worn distributor where that wear has little effect on the timing accuracy of the electronic conversion. I am sure it also helps that the electronic ignition systems run very long dwell for full coil saturation that is only otherwise possible with dual points, plus the electronic module will feed more primary current to the coil than points can handle without burning. I have installed a half dozen of the Pertronix units for others with good long term success, and have converted my hard starting 4020 gas to a home built point triggered electronic ignition system using Chrysler electronics.I used a point triggered system because they will fire right down to 0 rpm, while the magnetic triggered ones will not. This is a hot, high amperage system that makes it the great starting, good pulling tractor it should have been since new. At the same time, my Big Mo 400 Moline starts and runs just fine with the stock point setup.
