Keith- Great looking engine- looks original to me, hard to imagine its approaching 100 yrs old.
The dual Kingston carbs are unique, same as on the 4 cyl in above ad !
Thanks for the post.

Can you imagine the challenge of getting this engine to run right.
The cylinder nearest the water pump gets cold water, the cylinder farthest away gets warmed water. Under load , the temperatures of the cylinders would never be close so the mixtures would either be too lean or too rich for one of the cylinders.
The 2 cylinder Nadlers would be easier because they are cast enbloc and get more uniform temperatures.
But I guess maybe that's why they had 2 carbs.

Miro,
Maybe we should send the Vim up to Barry. He can put it on his Dyno and see if it develops the 35-40 hp stated on its tag and take cylinder and exhaust temperatures. What do you think?
Keith,

Getting it under load would be the right thing to do, to see if you COULD get it to run smoothly.
I suspect that Barry's dyno would quickly overheat
and become non-linear. But it would be one heck of a way to make a pot of boiling water for a tea pot.
Or maybe, just maybe , it could be put in a boat to see what it could do . . maybe one of the Louisiana flat bottom bateaux :-}
(I'm just looking for an excuse to get down there next March)

My backyard dyno uses a tank containing maximum 300 lbs of water
It‘s interesting to note that a 25 HP engine loaded to RPM that results in maximum torque would increase the temperature of 300 lbs (36 US gallons) of water 21 degrees F in 6 minutes.
For an engine of this size a load wheel about 20 inches diameter and a test tank containing 1000 lbs of water would be about right.

Hello, looking at buying one of these, but it is missing piston and rod, how hard is it to come up with piston and rod. Are they available anywhere.
