What size and type of carbies do you have? What size motor have
you got? What RPM do you want maximum power produced?

If I were to guess, here are some likely scenarios:
1. 1600cc motor, 40mm Del'Orttos, max power at 6000 RPM.
   Choke 31mm, Main jet 125, idle jet 45.
2. 1600cc motor, 40mm Del'Orttos, max power at 6300 RPM.
   Choke 32mm, Main jet 130, idle jet 45.
3. 1600cc motor, 40mm Del'Orttos, max power at 6500 RPM.
   Choke 33mm, Main jet 135, idle jet 45.
4. 1800cc motor, 40mm Del'Orttos, max power at 6000 RPM.
   Choke 33mm, Main jet 135, idle jet 45.
5. 1800cc motor, 40mm Del'Orttos, max power at 6300 RPM.
   Choke 34mm, Main jet 140, idle jet 45.
6. 1800cc motor, 45mm Del'Orttos, max power at 6500 RPM.
   Choke 36mm, Main jet 145, idle jet 45.
7. 2000cc motor, 45mm Del'Orttos, max power at 6000 RPM.
   Choke 36mm, Main jet 145, idle jet 50.
8. 2000cc motor, 45mm Del'Orttos, max power at 6300 RPM.
   Choke 37mm, Main jet 150, idle jet 50.
9. 2000cc motor, 45mm Del'Orttos, max power at 6500 RPM.
   Choke 38mm, Main jet 155, idle jet 50.
However, the above are only guidelines from a program.
It is best you have your car dyno tuned and get it sorted
out in "real world" conditions.

Seeing that you are in Melbourne, ring Vin Sharp
and ask him. Also, join AROCA and ask some members
who race - they have "been there, done that"!
