'What make engine is this?' asks Mr. Somers. Anyone know?

In response to question of Michael Bukovac in July & August GEM issue on page 32, I am enclosing pictures of a Johnson ultmotor No. U-3-6085 of Wankegan, 111. -- picture No. 1 engine in front. My engine has an aluminum flywheel and a vacturi carburetor. I am not sure of make of magneto. It is identical to the Maytag with Pat. year of 1918 and 1921 in the top row in the rear in picture No. 2.

Picture No. 2 front row to left is a Jacobsen No. M31005-16 manufactured in Racine, Wis. This engine has a cast iron flywheel rope starter pulley and Wicomganeto. This magneto was manufactured in Springfield, Mass.

The two cylinder Maytag left backrow picture No. 2 has a Eismann magneto manufactured in Brooklyn, N. Y.

The Johnson motor has linkage hooked to kick starter as long as you hold starter down it chokes motor and it won't over choke it because it has an air drag valve above. The governor is on point cam like the Maytag. The Johnson starts very easy and runs very nice.

I can't tell where the Johnson was used. It has a standard cast iron V pulley bolted to flywheel hub. The color of paint is dark olive green. I think the Jacobsen was used on a real mower. You can see where the chain was scarred on the cast iron gas tank. The color of paint is turquoise.
