I am hoping for some info on what jets / springs / rods etc to start out at .
I run a 400m with FMX and 9 inch (2.75 gears) in my '53 F100 .
It'll be close right out of the box with these parts....
Metering Jets - Primary .100, Secondary .095; Metering Rods - .070 x .047; Step-Up Spring - orange (5" Hg).

Use this Owner's Manual to fine tune it....
