Reader M. Moyers writes in, sending photos of some of his scale gas engines and a conveyor he built to make loading and unloading them for shows easier. We think the conveyor is a neat trick, and love the cam-stopper Callahan. “The flyballs disengage the camshaft when the engine is up to ...

   Faced with replacing two broken valve springs on an ancient 4-cylinder engine, I found springs of the correct diameter and correct wire size. The stock spring was longer and stronger, so I gambled on some homegrown metallurgy. The replacement springs were fully compressed with bolts and ...

I purchased these negatives at auction. They were taken around 1915 to the early 1920s. The first one looks like a Stickney on a saw in a hog yard, and the second looks like a Novo, hooked to a small Ferris wheel under construction. I believe both were taken in southeastern South Dakota.Dave ...

 I have a conundrum I hope you can solve. I think this is an early Novo S. As you can see in the pictures, this unit has no breather tube and it also has no breather holes in the back bearing cap. It does, however, have a small breathing pipe on the backside. Also, the castings have S numbers ...

My dad bought this engine sometime between 1915-1920. He used it in the 1940s for various chores around the farm. The last duty was to run the clothes washer. The washer sat on the porch and the engine sat out in the yard connected with a flat belt. Sometimes my mom had trouble starting it, so ...

I have found a Remington oil engine in a barn. I don’t know whether to buy it to restore, or sell it as is. How rare is this engine? How much is it worth as it sits, running or restored? I saw this engine for eight years as I picked up my milk. I always loved it. Now the farm is sold, and the ...
