About June of last year, I acquired the little Stover K engine shown here. The engine is 1 HP, rated at 500 r.p.m. It was sold by the Krakauer, Zork, and Moye hardware store of El Paso, Texas and Chihuahua, Mexico. Engine collectors in the southwest U.S. are familiar with them. I think they are still in business as Zork Hardware.

According to some Stover serial number data I got somewhere, this engine was built in the very early part of 1912. The serial #K36349 should place this engine in the first three year run of the K model when they were still only 1 HP instead of the later 11/2 HP.

I think this engine was built a little too early to have come with a Webster Tri-polar magneto, but the bracket #A303M20 is correct according to the December 1986 GEM lists. I suppose some industrious owner got tired of batteries and retrofitted a field kit in the past. I also have an eight cycle Aermotor with a retrofitted Webster and bracket. That engine has only a 3 digit serial number and is possibly as old as 1909. Anyway they both look good with Tri-polars and run well on them. My engine did not have a carburetor when I got it, and I think it might have used the three bolt mount. I had to use a later four bolt type until I get the right one. The overall condition of the engine indicated that it was not run to death. No wear was found on any of the shafts supporting cam followers, latch outs, etc. Bearings were all original, and the bearing adjustments had not been filed down to adjust clearance by any of the previous owners.

The flywheels of this K are heavier than the 11/2 HP models. The faces are about 1/4' wider. At one time, this engine was a little temperamental for an owner and got 'beat up.' There is a several square inch area on the flywheel faces just covered with deep 'dings.' It seems about one in ten of my engines have suffered a beating. I find that the owners did not tend to beat breakable parts, like mags or spokes or carbs. I used to think the marks were from being used as a temporary anvil.

Note that this engine was equipped with the optional butter churn pulley, available only from the factory according to Mr. Wendel.
