My friend Kenneth Scales of Oklahoma City, Oklahoma, has asked
me to send GEM an article on an engine that has never been featured
in your magazine.

The engine is a Lauson, model RLC, and was sold by Montgomery
Ward as an L C between 1940-1942. It is rated at HP at 1800 r.p.m.
and up to   HP at 3000 r.p.m.

The main bearings are ball, with a bore of 1′ and a stroke
of  1 7/8‘. Connecting rod bearing
is ‘ x ‘. Wrist pin diameter is
7/16‘, diameter of valves V4’. There
are two compression rings and one oil ring. Diameter of power
take-off shaft is 5/8‘.’ Shipping
weight is 32 lbs. Fuel tank capacity is one quart. It sold new for
$24.95. The engine is painted more an orange-red than mine.

What makes this engine rare is the rectangular gas tank mounted
on the front of the air shroud. It is sweet running and runs all
day with no complaint.

I thought maybe the kick-starter set-up would be nice to show,
plus the whole engine.
