R. R. 1, 185 Hysert Road, Grimsby, Ontario, Canada L3M 4E7;

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.
