20 Most Recent Farmall Cub Tractor Radiator Questions & Answers

Be sure the rod from the governor that attaches to the carburetor is not causing the froze up problem and check throttle shaft on carb. The governor does not give much trouble with freezing up.

Yes - I suspect your cam is 90 degrees out of time. This will have all the valve events happening at BDC rather than TDC - which equals zilch on the compression guage.

If the cam and crank are not marked, proceed from first principals - pick a cylinder. Position the piston at TDC on that cylinder. Rotate the cam until BOTH valves are off their seats. This is the overlap at the end of the exhaust stroke. The engine is now timed well enough to run - it cannot be more than 1 tooth out in either direction.

You will need to ensure that the ignition is timed also.

Read through entire article and first determine how far out of adjustment, stuck, or worn out the governor is. If not stuck or worn out, try adjusting.

Be careful after first start. Be prepared to shut it down immediately if it runs away. Not likely, but it can happen if some gross mistake is made.

There seems to be plenty of information available online - the wiring is relatively simple and basic, though the 6 volt version with a 4-wire regulator is a little more complex. The 12 volt conversion with a single wire alternator could hardly be simpler. It seems the ignition is by magneto. Apart from the stop control these units are self contained and if the engine has a good cranking speed and the magneto (and engine) is in good order the engine should start. The magneto is usually reliable with just the contact breaker points needing periodic attention. When the magneto fails it is a task for a specialist to sort out as a rewind is often needed...
