This is a 1929 Oliver Hart Parr owned by Eppinga Oliver Dealer,
Rock Valley, Iowa. Benjamin Henry Gesink is on the tractor.
On page 23 of the May-June issue, Mr. Krueger states that Avery
on Page 22 of the January-February issue is a 20-35. I am almost
sure it is a 12-25 H.P. which was built from about 1912-1922. It
had a 19?x 7′ pulley while the 20-35 had a 16 x 7?’ pulley
and had fenders covering the front half of rear wheels. The Twin
City looks like a 12-20 or 17-28 H.P. I am checking with Mr.
Blomgren to find out about pulley size.
Recently the mixing valve on a stationary engine was put
hopelessly out of commission, and a very simple but effective one
was constructed in the following manner.
A piece of one-eighth inch copper tubing was connected to the
gasoline pipe above the check valve. The free end of the pipe was
flattened nearly flat, leaving a hole about the size of a large
sewing needle for the gasoline to flow through, and then was
inserted through a one-fourth inch hole in the intake pipe above
the regular mixer connection. Then, in place of the old mixing
valve, a discarded motorcycle throttle valve was screwed on. When
this valve is closed the suction on the spray nozzle is heavy,
permitting easy cranking. Then the valve is opened some, until
enough air passes to make a good mixture. Of course any form of
adjustable air intake would do. But this device was made of old
material.
Here is a picture of two little gas engines that I made of
pieces of steel. They don’t run but look rather nice on a
corner shelf.
This is the 1947 Model B. K. John Deere gas tractor I am working
on at present.
