Every year, the 2nd weekend in october, we go to the National Apple Harvest Festival at South Mountain Fairgrounds Adams county PA. There was a 25 hp hit or miss engine running. Got pictures and video.











If you click on the last 3 pictures, they should run.

Arent those engines fascinating! We have an antique motor and tractor show here each year. Mostly oldtimers display their hit/miss and there may be 20 to 25 popping off! I stood and counted the flywheel rotation on one. 8 rotations between firing. The antique tractor pull is cool too.

I love old stuff like that!  We have the Antique Farm Equipment show here every April.  Lots of cool stuff there. Wink

I've got video somewhere of one of those hit or miss motor Ice Cream maker wagons. Pretty neat. Let me see if I can find that file...

Mike, have you seen this engine up in Oregon? Don't think it is a hit and miss but is sure fun to watch. Has a nice beat to it AND BLOWS SMOKE RINGS...

I think they're cool to watch. There are a lot of shows in our area.



I asked the guy where do you get rings for it? He said some guy in Long Island had them for $50.00 each. If they would have been $75.00 each he would have made his own from cast iron pipe. Interesting I thought.

MasterCylinder, yes I have. That monster diesel engine is sitting on the Pottsville grounds where the show I mentioned is held each year. It is even larger than you might think from the video. It is started by filling a large compressed air tank with a small 15-20 hp gas air compressor. Then when adequate pressure is reached a valve is opened, the big boy turns over, and fires.



Not far from it is another large, but not as large, engine that would have been used on old oil derricks. I was watching it run and noticed one of the big exposed 1.5 in.(+) diameter pushrods wasnt rotating. Asked the guy tending the thing about the cam and he said it is bad on that lobe, and he just gives the pushrod a shot of oil and rotates it by hand when he can.



The cam would be a little too long for most cam grinders, maybe 6feet.
