Farmall C - - govenor hunting

Anonymous-0 · Jun 13, 2010

Guys -

Son just reassembled a C after a mild overhaul (pistons & sleeves and a valve grind). At most speeds the govenor does not hold the engine steady (while the tractor is still in the barn). It mildly hunts, doing kind of a brump-brump-brump-brump, about every second. If I hold the linkage still, it pretty much steadies out.

Looking for some ideas as to where to start looking to this hunting.

Thanks !

Pete

Check the Carb. I had the same problem and it was guncked up.

Before getting into the carb, try resetting the linkage between the governor arm and the throttle lever on the carb per the manual. It doesn't take much to get that off. Just a little movement in the new position of the head or the manifold, or where the carb hangs off the manifold, from where it was before, can make a difference.

Motor stopped, throttle lever at the seat full forward (i.e., high speed). Pull the pin out of the clevis at the front of the rod between the carb and the governor arm. With just enough pressure to meet the tension from the governor, hold the governor arm back. At the same time, push the rod to the carb back as far as it will go. With everything in that position, thread the clevis itelf on the rod so that everything lines up so that you can slip the pin back in.

If that fails, there's the adjustment to the bumper spring on the underside of the governor housing.

Never been into a C before, but the exact issue you are describing is usually a weak gov spring or a mis-adjusted gov on the H's and M's.

When you fix it, post here to let us all know what it was exactly.
