(quoted from post at 03:43:02 05/21/12) My 640 has been running for 24 years on the same points.I check the gap when the spring work starts.Ive had the engine shut down twice.Clean the points with a pocket knife, running again.When you are trying to get your hay in theres no money left to buy a rip off solid state ignition.
24 years? I have to question that. Point life is not measured in years......nothing mechanical really is. It's hours.......and by nature points are going to go bad. No exceptions. Don't believe it......pop the cap off and with the ignition switch on, points closed manually open the points. Sparks fly. That alone is going to wear the contact surface. Plus you have a poorly lubbed system with the rub block on the lobes.
LOL I wish it were only once a year. 1 set of points a year but to keep it running at it's best I'm pulling the dizzy and cleaning and gapping the points 2-3 time a year besides the change over to new points once a year. Course I could figure the labor at a higher rate and pay for IE in one year....LOL

If the lobe wears to the point that the tractor dies and you have rain coming and your hay needs baled........I only use my gas tractor to rake and move hay. But if the pump goes on my diesel when that hay is on the ground I'm in trouble.......my gas tractors ain't going to help......my round baler require 70HP.
Just seems my BS dector is about pegged.
Changing points on a flat head car or truck is a lot easier than on an N tractor.
Mechanical skill? Where did that come from??????? First mechanics task I learned was cleaning parts........2nd was changing points and doing tune ups. So back in the day the skills needed to work on points was right above cleaning points and about changing oil. Correctly setting points is more of an attention to detail thing than a skill.
Now I figure that time is worth money and that everyone's time is worth at least minumum wage. So between pulling and setting the points, plus new points one a years on my N, between cash outlay and time it's costing me 50 bucks or so a year to keep points in it (that's at minumum wage not the 22.50 an hour I made as a mechanic). So if IE last 3 years it's paid for itself, 5 and I'm money ahead and have more time to go fishing or something.
