Farmall Super-A starter

Postby farmalllove » Mon Feb 17, 2020 4:19 pm

So I've recently inherited another Farmall, a Super-A, and its been running great mostly. I had some initial work to do, it had sat for two years without running, Cleaning the carb and fuel system. The first problem that kept it from running ended up being corrosion on the contacts in the cap, and on the points. After all of that, it ran great for a couple months. Now I am having trouble getting it started. With the ignition switch pushed in, and pulling on the starter rod it turns over great and at a very good speed. Whenever the ignition switch is pulled out to the run position, the starter cannot turn over at any real speed, it lugs along part of a rotation at a time (with the compression of the cylinders). Any ideas on what the problem could be or where to start looking? I've tried two nearly new batteries from my other Farmalls and they have proved no better. All my batteries are kept inside on battery tenders over the winter.

Ignition timing. Better yet, complete engine tune up.
I have an excuse. CRS.

Have you tried cleaning the connections on the ignition switch?

It has new cap, rotor, points, and condenser as of a couple months ago, they are all clean. The tractor idled perfectly and ran great before, it seems to be a sudden problem and not one that has gradually worsened. I'll try cleaning the ignition switch's contacts up and see if that makes a difference.

Yup, always go through the simple free stuff first.
Clean all your electrical connections including your grounds first. If it wasn’t the problem it was going to be. ;)

sounds more like timing as you say it spins fine with the ignition off, when you turn the ignition on it puts a load on it, make sure your firing order is correct, if this has a distributor make sure the advance weights are working correctly, seen many that are frozen and broken springs

After cleaning the contacts of the ignition switch I was able to get it to start. After driving it awhile, I shut it off and started it again. It acted similar to it had before but to a lesser degree. Thanks for the help, when it warms up some more, in a couple of months, I will do a tune-up and replace the spark plugs. This spring/summer I will rewire the whole tractor. Thanks again for the help.

I agree with Tim on this, If the advance is frozen or the springs broken or weak, the distributor will tend to stay in the advanced position and will push back at the starter, causing the cranking issue. When you do your tune-up, remove the distributor and fully service the centrifugal advance mechanism. After reassembly, time the engine with a timing light, paying particular attention to idle timing and full no load rpm timing.

As several have said, check the timing. Static time it at 0 advance. When you have time/weather later on, check that the advance is working as previously suggested.
