Judson engine

Inspired by Bob Elliot's photo of his C.S. Judson engine in the February 1986 issue of GEM, I am enclosing a couple of photographs of a Judson engine that was finally brought to the point of reasonable restoration in late summer, 1985.

This Judson (Stover) engine is a 7 HP throttle-governed engine equipped to run on gasoline or kerosene with water injection from the hopper. The bore is 6' and R.P.M. is 360. Some other features are a Webster magneto with self-starter and a 20' diameter clutch pulley. The serial number on the original name plate is RX89045 which, I believe, dates the engine at 1916 or '17.

This engine came to Minnesota from the vicinity of Wynyard, Saskatchewan, where it was owned by a gentleman by the name of Barry Stachyuk (my apologies for any misspellings). If Barry is a reader of GEM, it would be interesting to hear from him.

When I obtained the Judson a couple of years back, the carburetor was functional on one valve only, the igniter trip was jury-rigged, the fuel pump was 'shot' and two of the four piston rings were broken. Surprisingly, it would run! For a few minutes on gas from the starting tank, anyway.

The mentioned problems (and a few others) were taken care of in turn and a reasonable facsimile of the missing (as usual!) half-moon crank guard was shaped from a small trailer fender. All bearings and gears were in good condition.

Final cleaning did not reveal any remains of original paint. The information that I have on Judson indicates that the engine may have been painted green, red or black. I was tired of green and didn't like black.

After a few minutes' warm-up on gas from the starting tank, one can switch to kerosene (with a bit of hot water added through the carburetor water valve) and the engine runs well making neat little smoke rings which help to keep the Minnesota mosquitoes at a respectable distance!

The Judson can be belted to a 30' cord wood saw (not shown in the photos) and can handle about anything one cares to lift to the saw if the teeth are kept reasonably sharp.

If someone out in engine land could help, I would like to know the correct length of the carburetor overflow standpipe, as the one in the carburetor of this engine was completely rusted away.
