MAG473 Posted November 19, 2014 Share Posted November 19, 2014 I was comparing my 1913 Metz "22" engine to a 1915 "25" block that I have. In addition to the larger bore I found the cylinder height of the 25 to be approximately 3/8th inch taller. I don't have "22" rods but have "25" rods to use if they are the same. But either the piston height, rod length or crankshaft has to be different. Anyone else have any ideas?Wayne Link to comment Share on other sites More sharing options...

The parts list shows connecting rods to be the same part number, crankshaft is same part number, cannot find a cylinder assembly part number for the "25" model. I may have to have the connecting rods modified to get the correct height.Wayne Link to comment Share on other sites More sharing options...
