Thanks Grumpy. No chromed bore on this old girl, she's about a 1979 manufacture date. I put a new gasket on when I replaced the piston and rings. I had a look at the piston and rings and they seem fine. Like I said, once it is started once it can be started every time first pull and it was never hard to start before. The carby doesn't have a prime system and was actually replaced not long ago so that shouldn't be a problem. I might lift the cylinder and check for any damage to the gasket and retension the allen screws. I'll also check the fuel line in case I may have nicked it during the rebuild. As to aero, I use the one specifically for 2 strokes, I'm guessing it has some lube built into it.
