I just picked up the remains of a New-Way two cylinder horizontal opposed engine. The flywheels are 26" in diameter and the crank throw makes for a 6" stroke.
At the auction I was thinking I could get some listeroid cylinder and piston sets and make a nice smooth running engine. But after looking at it more I think the crank is a bit weak for such use and the 6" stroke may be more then the listeroid cylinders could handle.
A bit of research shows that the engine should look like this.

http://www.cadl.org/localhistory/auto/newway.htmAs you can see it was converted for use as a wood splitter. With that type of use I was a little concerned that the crank may be bent. At the auction it was sitting with the flywheels on the ground so it was not possible to turn it over to see if anything had an unwanted wiggle. I have since disconnected the connecting rod to the splitter and loosened and lubed the main bearings (they look like they were repoured not very long before they stopped using it. So now the crank would spin easily and when this is done both flywheels run very true, better then I have seen on listeroid engines.
This engine was throttle governed but only the exhaust valve was activated by the cam the intake valve was just a check valve. Also I believe the ignition was a low tension make and break so overall not much removed from a hit and miss engine.
If I can not find original parts I may fit a set of air cooled cylinders from a more modern engine. Need to find some with a 4.5 to 5" bore.
Since the original cylinders were mostly covered with tin and the rest of the parts could be fabricated to look much like the original I should fool most people.
The other option would be just a free style one off engine. I think a two cylinder gearless hit and miss with pendulum type governor would be fun.
Note the star wheel and ratchet used to get the four stroke cycle.

I have found that one of the flywheels has a broken spoke and I will need to look for another wheel. The wheel with the groves machined for the fan belts looks to be in good shape so the engine can be built and run without the second flywheel or with something else in its place until a wheel can be found.
Should I mention possibly repairing the broken wheel.
Yet one more project.
