Have you replaced the ignition switch? After time the switch can start acting intermittently. It will test "good" with a static continuity test but then during operation cut out intermittently. You can bypass the switch altogether by disconnecting from the leads and directly connecting the wires together and then starting the tractor to see if things improve.

My neighbor who's a retired mechanic tested the ignition switch for continuity and jumped the connections. No change. I will reconfirm with him. Thanks

I HAD SOME PROBLEMS WITH ENGINE PERFORMANCE ON A 9N.AFTER REBUILDING AND STILL THE SAME. I DISCOVERED IT HAD A AFTER MARKET COIL AND THE RESISTER TO THE COIL WAS JUMPED. REPLACED WITH FORD PARTS AND IT RAN WELL. DOES THE COIL MATCH THE 6 OR 12 VOLT BATTERY? NEG. OR POSITIVE GROUND?

I bought the tractor from a guy who restores 8N's and he rewired the entire tractor and did a professional 12V conversion with the kit offered from Redbelly Tractors - Restorations | Just8N's.

The alternator has an internal resistor and the coil is an automotive 12v design. Not knowing how to test the coil properly, I bought a new 12v coil from tractor supply and replaced it. This didn't fix the problem.

I'm aware that some 12V conversions are hack jobs and some don't replace the coil with a 12V design, but my conversion seems to be done right and it ran perfectly for two years.

Good copy on all that. Thanks

A mechanic with hands on can make more headway in 30 minutes than a dozen can in a week on the net. You might think about paying him to fix it and save yourself some grief.

Yea true, I'm just hard headed and like to fix things myself. I know if I take it to a mechanic it'll be some little thing that I missed and I'll be kicking myself. But the fields haven't been mowed in a couple months and you're right I may be better off just paying some one to fix it.

My brother and I had an 1800 Oliver given to us,previous owner said his mechanic friend told him the motor was blown. Ran but barely missing and popping, could only get it started by pulling it. Did most of everything you have stated and ended up buying a brand new carb. Long head ache short the coil was bad and the new one was also. Bought a second new coil and the old beast runs like a top. Not sure what the chances of that happening are but figure I would mention for what it's worth. BTW both coils showed spark when we checked.

I've read the first of three current pages and can't wait to see how this turns out.

Far more often than it should. Points and coil ignition hasn't been used on cars for over 40 years so quality control during manufacturing is almost non-existant today. Unless a person know's how to test components they have no way of knowing which part was bad to begin with and if replacement is bad.
