Disabling a governor is a good way to scatter an engine, as its main purpose is to prevent over-revving in the lower gears. That's particularly true if you've got a bunch of gears to play with, like a Brownie and/or a 2-speed rear axle. In the first couple of gears, especially on the low side of a 2 speed, the engine will max out the RPM before you can make a shift. Engine torque (or lack of it) usually holds the top end speed down, not governed RPM, especially when hauling a load.
