I have a Super WIZ that I rebuilt. Having troubles getting it to pass the 4k RPM mark

Starts right up after sitting overnight
Upon throttling, the saw sputters at about a 3-4k RPM limit, lots of smoke from the exhaust, Compression 138psi wet, appears that timing is off or running really rich, running 45:1 mix with non-ethanol fuel
What could cause this? See video below for context
