Tips on troubleshooting the gas engine.
Mr. Lewis H. Cline of Battle Creek, Michigan,
has replied to the inquiry of L. E. Rapp about the Johnson
Utilimotor. Lewis has a Utilimotor No. U-13318 which furnished
power for a Sears Roebuck wooden tub dolly-type washer made in the
mid-20’s. He states that the engine wore out the washer and
is still in very good shape, and that he has the instruction
book.
Some advice when troubleshooting the gas engine. Fuel mixture: One half pint of medium heavy oil to one gallon of
common gasoline or one part oil to sixteen parts gasoline. Magneto
breaker point setting: Ten thousandths of an inch or use the small
plate on flywheel which is .010 inch thick. Every 90 days add a few
drops of oil to small cup at top of crankcase. Spark plug gap: .025
inch. Fuel adjustment: With the motor stopped, loosen the set screw
in needle valve with a small screwdriver. Then with screwdriver,
screw needle valve in until it stops. Turn needle valve lever to
the right against stop and holding it in that position turn the
needle valve open five-eighths of a turn. Then lock the set screw
in the needle valve lever. The choke plate should fit tightly over
the air inlet, shutting off all air when motor is being choked. The
choke plate and needle valve lever are connected together by a link
on later models and the automatic choke model has the choke linkage
connected to the starter pedal. Earlier model has separate choke
control directly connected to left-hand thread needle valve. When
the motor is choked the mixture will be made richer by needle valve
being opened slightly.
This is the mill I am using now. It was 6 years on August 8 that
I used it the first time. It is very rigid, feeds very smoothly and
cuts good lumber.
If flywheel is removed, be sure on replacing that the drive pin
enters the elongated hole in the rotor to the right of the breaker
cam, sighting thru the opening under the plate in the flywheel.
These engines are hit and miss governed, and when under no load
will not fire regularly.
Mr. Cline suggests trying Hastings Mfg. Co., Hastings, Michigan, for
rings or Outboard Marine Corp. Thanks to Mr. Cline for this
information and for passing it on to us.
I still need information on the Rock Island engine and the
Swartz engine.
On page 32 of the Sept-Oct Gas Engine Magazine under the What Is It? column is an
engine belonging to Ruben Michelson that appears to be a Sattley
sold by Montgomery Ward. Question: Does anyone have any information
on the Sattley Company?
This summer is gone and most of my spare time was passed
rebuilding my faithful old jeep, but the engine collection has
gained a couple of Sattleys, and Alpha (DeLaval), a Fairbanks Type
T upright, a Dempster, an Ottowa, a Fuller & Johnson upright
air cooled pump-jack engine and many miscellaneous items including a piston
type boiler pump, a McGowan steam boiler pump, several forge
blowers and blacksmith equipment. I hope all of you have as much
enjoyment from your engines and equipment as I do from mine. Thanks
again for your questions, your answers and your interest.
