Low compression causes

Low compression causes
Have a 2 stroke ATV and I just had the cylinder rebored and a new piston and rings. I was very careful to install the cylinder so the rings didn’t move off their pins. I also checked the ring gap before i assembled and all was well within spec.
I’m pulling using pull cord and I’m only getting around 80psi most of the pulls. One or two pulls I got close to 100. Spec on my 1986 Polaris trail psi.
Is this because I’m a weakling and not pulling hard enough? Or could it be something in the bottom end? I am no expert but though a compression test from the spark plug only checks pressure of the head section.
Any suggestions what to look for next?
