I'm gonna check the compression again. It feel good when trying to start it. Checked once before and it measured 100 psi give or take a psi. Figured that was pretty good. I have good spark and fuel. Installed a bbr stage 2 ignition and a nibbi 17 for the fuel. Plenty of both (I think).compression, spark and fuel. Typically compression loss comes from the crank seals. Could be bad timing but even then it would run rough for a brief period.
