" I've considered going with pointless ignition to cut down on problems."

I'd consider annual maintenance on the points before I'd consider EI.

EI will not work well at all on 6v (it won't fire below 5.2v) so you would need to convert it to 12v.

EI does not give you higher spark voltage, eliminate all maintenance on your ignition system or give enough of a horsepower boost to cause the tractor to do wheelies. It replaces the points. Thatís it. It will not correct or overcome other problems in the ignition system. While it may give you more HP or improve fuel economy, both would be so insignificant as to be hardly noticeable on a 23 hp engine. If you canít set points or donít care to do it, or you donít want to spend the 30 minutes or so a year to check the gap & lube the cam, then you will be happy w/ EI. And, the EI unit itself will be maintenance free. (but the rest of the ignition system wonít) You will spend probably $235 for an EI kit & 12v conversion. If you install them correctly you will have an easy starting tractor for a long time. And, the 12 volt conversion & EI will have just about nothing to do w/ the good performance. What will make the real difference is the new wiring, cables, clean grounds & new battery.

The key advantage to EI is that you do not need to gap & lube the points every year & replace them every 4 or 5 years or. If you perform annual maintenance on the points & change them every 4 years or so using quality parts, you will see no difference whatsoever between a points ignition system & EI on an N.

The key disadvantages to EI on an N are initial cost, nearly impossible for the average N owner to repair, will not work w/ low battery voltage, & easily damaged beyond repair by polarity reversal & other common mistakes.

Bottom lineÖÖÖ.this is the question you need to answer: ďIf tens of thousands of other Nís operate just fine on 6v and points, why canít mine?Ē

Your money, your tractor, your call........

From the late 1970s onward Everything built had Electronic Ignition in it.
Tractors, cars, pickups, snowmobiles, outboard motors, mototcycles, small engines, 4 wheelers,
EI is more reliable, does not require maintenance, spark does not degrade due to wear on points, dwell is more accurate and so better fuel efficiancy, better allows for wear on the distributer, plus other reasons.
12V EI for a front mount is $96 from this site.
Side mount kit is $77.
Decent set of points and condenser is at least $30 now. Likely more.
By your own estimate - 4-5 years on a set of points - the tractor I mentioned above would have needed 2.5 sets of points in the 7 1/2 years I ran it with EI. That is at least $75. Getting awfully close to the price of EI for a side mount aren't we?
Plus never having to touch the points again?

Bruce, with a regapped old plug. Do you connect plug to plug wire and then touch plug to block to check for spark and spark distance. Thanks wanting to make sure I understand.

Open the gap on the plug. Attach the plug wire. Hold the plug firmly to the block or manifold.

A plug checker is more accurate & easier to use for a number of reasons. But an old plug is cheaper!
