F3's are the correct item for E, Solex, S, and Mod-S cams.
F24's are the ticket for most race cams such as 906, GE-80, RSR Sprint, GE-100, etc. |
Port diameter difference is 3mm... my experience is they like to run a bit fatter on the mixture. I imagine we would be hard pressed to nail it perfectly on a keyboard but these are good starting points. Properly adjusting the linkage for the banks to match should be given as much detail in my opinion.
