Is it worth the money? And do you have to change the coil?

Kenneth, its your tractor n money n your choice, however, I can tell ya for sure an electronic igniiton has the capacity to produce more spark gap energy (plus a wider hotter spark) across the plugs gap to better ignite the fuel PERIOD. If youre gonna keep it a while n use it routinely, the elec ignition investment should pay for itelsf over the long run versus having to buy new points n condensor fairly often (depending on use).

ALSO theres less moving mechanical parts to wear out ESPECIALLY over an outdated cumbersome limited energy Magneto Ignition with its mechanical spring wind n trip impulse assembly plus the usual points n condensor wear as on a distributor ignition. Its true you cant do a jury rig field fix if she stops like filing the points BUTTTTT TT once an electronic device burns in they can last a long timeeeee eeeee eeee. One magneto advantage, however, is they can start without any battery which that elec ignition sure requires

COIL NO you can use your existing coil BUTTTTT TTTTT to get the most bang for the buck that elec switch has to offer I HIGHLY RECOMMEND YOU MATCH IT UP WITH A COMPATIBLE HIGH ENERGY COIL (like a Flamethrower) to get a wider hotter higher energy spark to better ingiite the fuel. Since that high voltage high energy coil has the capacity to fire at higher voltages, you can increase the spark plugs gap (maybe 0.035 to 0.045 or so versus 0.020 to 0.030) to get that wider hotter spark mentioned above you cant get using the old stock coil. There is some advanatge even with the stock coil due to the faster n more positive coil current soild state switching versus mechanical burning n bouncing n ringing points n condensor buttttt ttttt you get more energy plus can run a wider gap if using the high voltage high energy coil.

So pay your money n now make your choice

I put a petronics electronic conversion in a buddies SMTA hotrod puller and dont see a bit of difference. later,Hoss

I like the electronic ignition much better. No mechanical parts to set, clean, and wear out.

I recommend switching to the high output flame thrower coil. I was able to increase my spark plug gap from 0.022 to 0.042.

You don't have to change the coil. The electronic conversions I've seen don't require any modification to the distributor, just remove the points and condensor and put the electronic module in. Save the old parts in case the electronic module ever conks out or you want to go back to original, only takes a few minutes to swap them.

Just my personal opinion, but I wouldn't trade my old 1946 magneto for all the electronics in the world. With a 1/4 pull on the crank or a quick step on the starter, it's off and running. The best thing is that it is still all original equipment except for new points and condenser. It is almost "fail proof"!

My H was a bit of a hard starter, electric ignition took care of it.

I put it on my Super A and my B and they both seem to start better and are a little snappier when you open the throttle. I bought the coils for both of them that way I knew things would be right. Shaggy

Personally I don't think it is because a set of points are cheap and last for years. You couldn't possibly use enough points to override the cost of electronic in the life of the tractor. If it was a high compression puller then maybe. I know there are guys who swear by electronic and that is ok.. Electronic really shines on high RPM high compression computer controlled engines. I just don't think it is worth the expense for a stock tractor unless you are in competitive pulling.

One thing I can add to this is "marketing" has convinced a lot of people it is better across the board for every engine. on a low compression engine low RPM engine, you just flat out do not need 50,000 volts unless you want to screw up TV reception for a square mile. In a low compression low RPM engine the piston moves much slower and has the time to ignite the fuel mixture. In a High compression High RPM engine The piston moves much quicker and there is less time to get the complete burn, PLUS and this is the big point with high compression, The plug air gap acts as an insulator so if the specification is for a wide gap it must use a hotter coil, Higher compression, more air in less area, higher insulation factor. The last time I checked , most farmalls have about 6-1 compression and some older ones only have 4-1, and don't run at 8000 RPM (at least for long they won't) and that is a far cry from needing racing parts. Like one other guy said, it is your tractor and your money and I am not saying rip it all off and get rid of it, but I can see the marketing people smiling, they did thier job well. They have also managed to sell refrigerators to eskimos!(no kidding!) A set of points if everything is set right will last 10+ years. The points in Dads ferguson have been in for over 20 years worked hard every summer and not one problem, but we don't leave the key on when not running, that will cook a set. Here is a good example of Marketing driving a way of thinking. Bosch came out with the platinum spark plugs back in about 1990 or so. They had a HUGE marketing blitz about the benefits. Everyone and thier mother ran out and bought those things.Same thing happend with those "splitfire plugs", can you even buy those anymore?. (Platinum plugs are not a new thing, I have an ad from 1909 for platinum plugs) I was working in a shop doing engine runability and tune ups, and after a while when a car would come in with a miss, first thing I would do was pull out those botched bosch plugs. 9 times out of 10 it was problem solved. I wasn't putting in just one brand either, I put in the type that came from the factory whether AC autolite or champion. Some of the Bosch plugs I pulled out were brand new less than a week old. There is only one aftermarket igition system I have heard of that acually does improve performance in car and truck engines and it is the MSD, but in the average car the benefit is only minimum. In race engines, it is big! Sorry to rant, but hey guys, just be critical of what the marketing people "say you need". Chances are the CEO needs a new wing on the mansion to house his Rembrants.

''Monsieur, my son is eighteen. If he had not coverted his Farmall to a twelve-volt electronic ignition by the time he was twenty, I would have disowned him. If he has not converted it back by the time he is thirty-five, I will do it then.'' - Clemenceau.

Actually, Clemenceau was talking about Communism. But Communism and conversion to an electronic ignition system ''just because'' both appeal to me about as much.

Generally speaking, the older a tractor owner is, the more likely they are to stick with the original six-volt system rather than trash it because ''new, high tech stuff has GOT to be better than old stuff, right?''

Wisdom comes with age.

It's your tractor. Convert it if you must. But I don't think you'll see any improvement in reliability or performance to repay you for your cash outlay and efforts.

And, save the original parts. The next buyer might want them. Especially if he's an old guy like me.

You wouldnt be wasting time fooling with a set of points, not a big deal unless your siting out in the middle of a 200 acre field with no tools...Dont take it the wrong way, but sometimes you have to get with the times.While I agree wisdom comes with age, sometimes the younger generation has a better way of doing things, and the older genration thinks its not right.When given a chance, we just might surprise you!
