His point is to many times EI is put on to cover up other issues with a worn engine. I like EI and think it has its place but I will not have it on a tractor of mine. I have had conversations with to many folks that have converted from points to EI and have been left with a sitting tractor when the EI failed. One man I spoke with last year was installing his 4th after the 3rd one had failed on a machine that he installed new wiring and made a good clean install, yet they still failed.
Anyone who can read and understand the wear on a set of points can have a very reliable ignition system. A system that if something should go wrong in the field that can generally be fixed good enough to get back to the barn with a simple screwdriver instead of being stuck in the field with a burned out part. The art of setting points ignition systems is a lost skill like so many other things now days, done right points will run for years without issue. Plus I can keep a spare set on hand and/or replace several sets of $10 points for the cost of one failed EI.
