Hello, The Holy Spirit, spoke to my heart, saying for me to continue working on this engine I started 9 years ago, so as to complete what I started, and not abandon it just because I couldn't get it to work the first time.
The reason I couldn't get it to work the first time was I had very flimsy crankshaft journals made and no support in the middle between cylinders.
Now I made rigid crankshaft journals, and took the time to machine some parts to make a rigid middle support for the crankshaft to ride on top of, and did some lapping compound where the two met and now a very smooth running engine.
Here is a video of it working properly now.

Here is the utube version, just in case the above did not show up on video.
Following is the link to where I did a "work in progress" series of building this engine on this forum.

single valve, vee twin comp. air eng.
Most of my engines used a spring tension valve system, so when the air intake stops the engines would stop rather abruptly, my very first engine I ever built, and designed from scratch, was a double acting valve system, with scotch yoke connection for the valve. When I apply air to it, it revs...
