The W-D 13

I have built many models and my latest is a wild dream-a 13
cubic inch hit and miss.

About a year ago Dick Gibbons came by and gave me two 14′
pulleys that came out of an ice cream machine and said, ‘You
might want to build a motor.’ A year later I decided to build a
motor with a lot of moving parts. It’s a vertical motor with
two revolving side shafts. I found two sets of 90* drive gears from
a 1976 Harley Davidson motorcycle, the Zenith carburetor from a
lawn mower and I fabricated all the other parts. With suggestions
from many friends, I came up with this creation.

The left rotating shaft drives the water pump and the fly ball
governor. The right shaft drives the fuel pump and the cam for the
points. The pump pumps fuel to the carburetor and any excess fuel
goes back into the tank. The cylinder is water cooled and the head
is air cooled.

After about 800 hours I completed the motor. It is easy to start
and runs very smooth. This motor was shown at the Laurel Valley
Show this year for the first time. It drew quite a bit of
attention. The bore is 2.375′, stroke is 3′, compression
ratio 4.5 to 1, flywheels 14′ diameter, 4′ square oil field
tubing with stainless steel sleeve, head-aluminum, height is
34′, base is aluminum, width is 18′, .750′ crankshaft,
weight is 80 pounds.
