Very Low compression was created by PuttRider

I have a 1970 HT1 90 I'm working on. It was a basket case and a money pit, and this is my first 2-stroke project. It has extremely Low compression and of course won't even fire. I've honed the cylinder and installed a new piston & rings (2 rings). It's already been bored 2 over. I'm missing something here and am not sure I can even bore it out again as it's already 2nd over. It does get a good spark .    Any suggestions? Thank you!
