This is based on Vince Gingery's book "Building the Atkinson Differential" and was built in 2008. Patience is required to get the linkages just right and building a wood mock up is very helpful. The payback is a nice starting and sweet running motor. 1 5/16" bore with 1/2" compression stroke and 1" power stroke. O-rings on the pistons and running on propane. The flywheel is machined out of a 10 pound gym weight.
