It seems as if you have everything right where it needs to be. 92 psi compression is good. That mist you see coming out of the spark plug hole is good as well as that means you are getting fuel into the cylinder so long as it's not so much that it's flooding.

Are you sure that you are getting consistent spark? When the ignition modules on those carts go bad they will provide a spark or two here or there but too sporadically to lead to a running engine.

If you are sure that you are getting spark then your issue is almost assuredly the crank seals. Crankcase vacuum is critical in that, even though you are getting fuel to the cylinder, crankcase vacuum is needed to get it past that point. I would think that you would get an ignition or two here or though which I why I mentioned double checking your spark consistency. Still bad crank seals can cause many issues on a 2 stroke.
