If you took the back of the inlet out 10mm it would have a bit more torque and uphill pull.

While in there fit the carb box and blend it all in together. Some have some nasty edges between the two.

I would be concerned about using that old crank. It may be fine, it may not. Assuming its tight now and no visible rust in there, the proof will be in a few hundred miles time.

While in the cylinder with a Dremel it would be rude not to dress the exhaust port. The original intention is 38.8mm from deck to the inside of the port. If its less don't worry but if its more you could do a bit of 'blueprinting' (for a bit extra 38mm holding the same shape has good results).

Edit: btw that rotary inlet is fine. There are way worse running very well. The marks are just from an overheat, probably the same time the piston was damaged. I would assume from a lack of 2 stroke oil.
Thanks again for your insight - I sure appreciate it!
