It's real easy to start the Hubbard now. I crank it over a couple of times with the switch off to bring the air/fuel mixture up into the combustion chamber. Then I turn the switch on, bring the flywheel around to 11 o'clock where the points break contact, and away she goes.

I use a 32:1 gas/oil fuel mixture, as well as an oil lubricator for direct lubrication of the wrist pin and rings. The oil lubricator is set at about four to five drops per minute.

The main bearings and connecting rod bearings are lubricated with grease cups containing an extreme pressure water resistant farm/industrial grease.

Spark is obtained from a 12-volt garden tractor battery through a low voltage coil.

This old Hubbard can also be run on diesel fuel or kerosene, whichever was more available at the time. Many of the old-timers from back home who were familiar with this engine, and others like it, told me how they would start the engine on gasoline, then switch to kerosene after it warmed up, and back to gasoline just before they reached their destination.
