electronic ignition on 350 and m?

pt756 · Oct 23, 2016

took the m down to the neighborhood repair shop hasn't failed in 20 years but now needs some work done on ignition asked the guy to pit on the electronic ignition what does that all eliminate and would also like to do the 350 if I ever get it back together this fall, any advantages or disadvantages?

I put it on my 300 a few years ago and love it. The tractor starts almost instantly. I seldom have to crank it more than a couple of revolutions and it is running. Most of the time it is less that one revolution. No longer do I have to clean the points when it sits for a couple of months or more over the winter time. Every spring the 300 would not start requiring me to clean the points to get it to run. Plus if you have any wear in the distributor bushings, there is no worry about the points changing their gap which changes timing and causes misses. No longer do you have to worry about burned contacts, rub block wear and condenser failure. I would never go back to points unless it was to make the tractor completely original.

No automaker would consider using points today. The manufacturers have made them rather robust and reliable. DO it. Jim

I have converted three M's to electronic ignition. Do it, no more points. Ellis

I agree with other posts. I have converted 2 tractors, a JD430 and SMTA Farmall, and converted my jeep over. I have no regrets, the 430 especially was hard on points so was always adjusting them. It also tended to foul plugs. both tractors I converted had already been converted to 12v neg ground. I got one of the Pertronix flame thrower coil to match the ei on the SMTA, the 430 had a newer coil so used it. Both start quickly.

They may have done away with points 40 years ago, but on ignitions systems DESIGNED FROM THE GET GO to be electronic.

This is shoehorning an electronic ignition into a system designed for points and condenser, and they haven't had 40 years to perfect the design.

Frankly I've heard of way too many failures to be comfortable with an aftermarket electronic ignition.

An electronic ignition conversion only replaces the points and condenser. The rest of the distributor needs to be in good condition for an electronic ignition to work the best. If the distributor shaft bushings are worn enough that the timing bounces around, an electronic conversion will not fix that. The same with a stuck or worn advance.

As long as I can still buy new points, etc., I will not convert to electronic ignition.

thanks for the replies called the guy today and will probably try the electronic ignition

I have had petronix on my 240 utility for over 20 years, use the tractor year round, have not had the cap off since putting it in. I run the tractors I buy with the point until they need replacing then buy petronix best
85 bucks you will ever spend and easy to put in
