This project is definitely going to be an experimental model of hopefully a slow running hit miss engine.
3" stroke (never built one with that long a stroke)
1.250 Bore (I had to go that big to get the connecting rod in the cylinder)
8" diameter dual flywheels. (The 5" ones just aren't going to make it. I will use them for some other project)
Side shaft cam. (A new build experience for me)
5.5 to 1 compression (maybe even lower to start with)
19/64" valves (To limit the engines power)
Fly ball governor
Any of these items may change as the build progresses.
I cutout the connecting rod today.

Right off the CNC machine.
This sucker is over 9" long.
I wonder if it will be strong enough for this engine.
Connecting rod with wrist pin ball bearing and 1.25 piston.
Well so far my measurements are working out and the crank shaft does turn.
I did have to taper the end of the liner for clearance.
The cylinder is not attached to the rails yet that's next.
Thanks for looking
