Jetting is a "black art" that requires a plethora of baseline decision.
Altitude
compression
cams
port size
exhaust (both primary size and muffler back pressure.)
ignition
desired red line and so on.
Everything matters. Including your driving habits
That said: here's where I would start.
32-34 Venturi (smaller is better for low end response)
135-145 Main
180 Air correction
60 Idle
F3 or F5 emulsion tube (F5 is generally better as engine approached 2.8)
