Oh but I can as did several other big time engine gurus. Even George Aldridge called them "Modern Slag Engines" in reference to the old GHQ and other junk of the past.
They had a crankshaft that ran on the plain aluminum crankcase, no bronze bushing, and were prone to wear there. They also chromed the piston and NOT the cylinder. They were huge compared to their counter parts in size and wouldn't fit any commercial motor mounts. The 45 was as big as most 60's.
As stated, finding parts at a reasonable price is going to be difficult if you can find them at all. Not worth the cost. Another problem the early ones had was too much cooling fin in the head so they ran cold and didn't idle well. They finally chopped off the fins and the engine looked so weird with the plug sticking up a mile. that's when they first got the bad name and it went down hill from there. Well documented. Even Mecoa's web site states that. Parts and engine no longer available from mecoa.
