The old Ms were very good tractors, but due to the size of the engine you need to make sure that the battery cables are in very good shape, the terminals clean and tight, etc. They crank over slow, but if the ignition, fuel system, etc. are i good shape they take off and go almost as soon as the first piston passes TDC.

to restrain the people, it is an instrument for the people to restrain the
government lest it come to dominate our lives and interests." Patrick Henry
