Vintage Small Engines

Back when quality and pride of manufacture were commonplace, small gas engines would last 30 or 40 years or more. There were many different brands, and all were distinct from one another--you could tell one brand from the other with a casual glance.

Small engines can be traced back to the earliest days of the internal combustion engine. They have been part of American culture since at least the 1930s, when they were called upon to cut wood, lift weight, and other useful chores. These gas-powered labor-savers found their way onto many homemade farming devices, such as pumping water and shucking corn.

Gas-powered small engines were once utilized to power home washing machines in rural houses that did not yet have electricity. Motors such as the Briggs WM (and others) featured a foot-starter to make it easier for women to start.

In 1953, they revolutionized the small engine industry by developing the first lightweight aluminum engine. Being lighter and less expensive than their cast-iron counterparts, these engines made gas-powered lawn equipment more affordable to post-WW2 consumers moving to America's new suburbs.

Points vs Electronic Ignition

Early model Briggs flatheads had a points-style system, where the flywheel magnets rotate past the legs of the ignition armature. On this type of system, the ignition is always on.

Somewhere in the 1980s, all Briggs & Stratton motors were converted to electronic ignition. Early engines can be retro-fitted if desired.

Tecumseh Small Engines

Tecumseh began producing small engines back in 1934. In 1956, they purchased the Lauson Manufacturing Company, who at the time, were also a popular small engine brand. Today, Tecumseh is jointly owned by Certified Parts Corporation (CPC) and Liquid Combustion Technology (LCT).

Gas-Powered Scooters

A motor scooter is defined as having a step-thru frame, flat foot-board, and rear-mounted engine. Although step-through gas scooters have been around since the 1890's, their popularity didn't start until the 1930's.
