The 1/2 VW engine.

37 hp 92 mm bore x 78 mm stroke 1037 cc 81 to 103 lbs.

45 hp 94 mm bore x 86 mm stroke 1200 cc 84 to 102 lbs.

This thing has been modified so much we should not be calling it that. I will call it the Casler engine after the man who builds them.

A rear view showing the oil cooler/manifold heater and magneto. A very nice installation. The alloy barrels.

Another very neat installation with a starter motor. I prefer the 37HP version with cast iron cylinders no alternator, starter motor or magneto.

The Legal eagle photos are from Oshkosh 2014. The electronic ignition pick up and the counter balance. A blue one ,I prefer the black one in the box.
