Get some .035" .037" accelerator pump shooters as a start. (or drill yours)
you need a lot of accel pump volume shot for a blower motor.
blower motors love timing at idle. Don;t be shy. More is better.

Blower motos want modest WOT timing under boost, on pump gas.
less is better. Thus the locked timing and or locked timing - progressive boost spark retard relative to boost.

Race gas can handle higher boot and higher timing under boost (little or no boost retard)
Don;t get gretty on pump gas. 6 to 8psi is plenty.
