Cam-Stopper is a side shaft that when in the miss mode of a hit and miss cycle actually stops the cam from turning with the exhaust valve open. Examples are the Callahan and Field Brundage engines. On some(Callahan), the entire side shaft stops through a clutching arrangement near the crankshaft where the side shaft gears are. On others, the side shaft keeps turning, but the cam shaft up near the head actually stops with the exhaust valve open. Not many of those around. Saw a Field Brundage at Portland.

Another example is the Columbus engine - one sold fairly recently in Pennsylvania. Very high dollar. Jim

I guarantee you will stop, and watch that cam if you ever see one in action.

I keep a roster on Field-Brundage engines. On my list are about 22 camstoppers from 6 HP to 35 HP. I own the only 35 HP Field, which stays at Baraboo. What are the biggest Callahan and Columbus camstoppers to survive?
