Does anyone have the specs on the size of the adjustable breaker point screw for a 1967 140? My 140 is dead in the field and I was going to dress and gap the points when the screw fell down into the row of potatoes below, never to be seen again. Thanks.

Your right. I noticed we have opposite opinions about electronic ignition. I switched out 2 tractors to electronic ignition but at the same time switched to alternators and the flame thrower coils. I've got less than 6 months on them and all I can say is they start and run much better. I'll maybe change my mind when one of the electronic ignitions fail, or maybe I should just buy a spare. If they last at least a few years I'll never go back to points. I appreciate your sharing that you've seen them fail. I wasn't aware of that.

Notice if the poster had electronic ignition he wouldn't be looking to replace a screw right about now.

Has anyone else had electronic ignition failures on their tractors? I'd be curious to know the approximate mean time to failures.

Nawlens: Oh for those small items we all dropped in the soil. When you reach my age and more so the age of my eyes without reading glasses, you only take those items apart on shop floor. I like those sheets of white material politicians use making their signs. Great to lie on and small items show up great.

Don't mind me, I tend not to get too excited about new technology. The automotive industry, and by that I include all devices with internal combustion engines, have in my life time tried to convince folks that each new model was more efficient than the last. I site my Buick and dad's Chevy. I did a lot of my farming with a 560 and 656, both diesels, the two most efficient tractors I ever owned. Total of 25,000 hours on the two of them. Fuel consumption never exceeded 1.5 Imp. gallons per hour. I talk with young farmers today, using twice the fuel for the same hp.

I bought a new 74 Delta 88 Olds, 455 4 barrel, and got 22.9 mpg (imp gallon) My brother got 18 with his 350 4 barrel Cutlass, A neighbor, got much the same with a 305 Chevelle. I had another brother, said he could get 23 on his S-10 Blazer if he tuned it up monthly. I don't think that old Delta was ever tuned up more then 4 times in 250,000 miles. Yet the powers that be tell us we should use smaller vehicles. In the 60s and 70s I bought two near new Pontiacs (full size), two new Oldsmobiles (one 88 and one 98). None of those cars were ever back to the GM dealers for anything, warrenty or otherwise. Today you hear folks running to the dealer almost monthly, with their damn little uncomfortable cars. Why, the price they are paying the car should drive itself.

Points on a certain 140 would never stay put, would drift, and it seemed I was forever messing with them. Not any more. Hence my appreciation for elec ig.

Hugh, I tend to agree about the electronic ignition. I have had several go bad on trucks. I have never had any trouble with the factory set up on these Farmalls. They have worked fine for generations.

George: I find it hard to understand statements like, OH it will last 6-8 years, especially when the guy just removed a system that lasted 40+ years. Folks generally are like that today and corperate America just love them.

We bought all America built tractors 40-45 years ago, now folks want orirntal replacement parts that only last 6-7 years. Then you get the folks, proud of the fact they paid more for a car, truck or tractor than their neighbor, when really all they are trying to impress us with is the fact they had the credit rating to buy it. A friend and I were discussing this just recently. Back in the 50s, 60s and 70s you came home thumping your chest if you were able to beat 20-25% off the list price of a motor vehicle. You try that today and they laugh you out the door, might even suggest you get shipped off to the funny farm.

Hugh, it is some of those things that make you go hmmmmm . I can't figure this electronic ignition out either. Some of my old junk is 50 and 60 years old and I have never had much trouble with the distributer with points and condensors. My logic is if ain't broke it don't need fixing. Maybe some of the difference is that I have to run my stuff as cheap as possible and just couldn't afford to convert the 6 or 7 that we use at any given time. If I only had one or two hobby tractors and a good job, I could fix them up to rival any show tractor.

I replaced that screw with one of those green ground screws that come with home electrical switches. It's 3/16" fine thread (about 20 or 25 threads / inch)and about 1/4" long (longer it will botom out before getting tight). The advantage is you can tighten with a ratchet.

Electronic ignition works better by the way.

Nawlens: Can you recommend that electronic ignition with a straight face? I've noticed some of your posts, and gather you are not a whole lot younger than I at 65 years of age.

In my lifetime, I've only ever had one distributor ignition let me down and by the way it was 48 years old. I've had 6 to 8 electronic ignitions let me down on the road, and none of them were 10 years old. One of them was a 3 year old 98 Olds with 403 engine and it died within 20 miles of a complete ignition ckeck up. The service center determined it needed plugs only, the day before.

Your going to have to do better than that to get me excited about electronic ignition. By the way my dad's 1957 Chevy 6 cylinder gave the same gas milage as my current 6 cylinder Buick LeSabre. Those cars probably weigh about the same, gee progress has been grand.

One more thing, I can't remember when I last put points and condencer in my SA. The only reason I remember 140 is I bought it 4 years ago and did it then. I did put a set of points and condencer in 130 when I replaced the distributor drive gears last Dec., only because it was easy at the time.
