Well I got the engine up and going with freshly ground valves and a sleeve kit. Put a new carb on it, and it purrs like a kitten now... Already put it to work...
There's one fly in the ointment though.
When I first got this tractor 15 years ago the generator system worked well on it. I remember I had to adjust the regulator and set it up right.
In the intervening time though, it stopped and my family (I live 250 miles from where I keep the tractor) took it to a guy who apparently put a new generator and regulator on it, and they say it's never worked.
I took a look yesterday, and it's a 3 brush alternator, and one of the brushes was in there kinda wonky, the adjustable brush. I straightened it out so the brush will run square on the commutator but lost the position of which commutator it's supposed to be on in relation to the other two brushes.
Also the regulator has two large coils with contacts and 4 connections something I thought was for a two brush generator...
So do any generator gurus out there have any ideas?
I see a few options..
1) ground the field and play with the position of the brush until I get voltage(it rotates around the commutator and has a setscrew on the outside fo the housing)
2) shunt the field to the armature brush and convert it to a two brush and then check the regulator or get a new one if needed.
3) get a new 2 pole generator.
Any ideas?
A farmall C wiring diagram would also be nice to have.
