The engine looked clean inside but I removed the cylinders and flushed the crankcase out. Got a fair amount of grit and aluminum flakes. While the cylinders were off I cleaned up the exhaust ports a little and then flushed them too. I reinstalled the cylinders and found the cylinder bolts were too long and bottoming out. I cut them down and chamfered the ends. Tomy said he assembled it at Toledo from a mt70 case and "s" cylinders but I still don't understand why the tappings were not deep enough. The screws that came with the 70 are the same length as used on the MT35.


Anyway, the notchy feel happens when both cylinders are torqued down evenly. If I loosen the carb side bolts on the rear cylinder the notchy binding goes away. Any suggestions?

Now that I have the carb/reed block I can make a 2 into 1 header and see how it will work with a KS 86 can. It might be better with a JMB can.
