Contessa tuning!

[Thatkevv]

From your guys experience, about what should the jetting be on my af16 with these mods:

Cp21 carb
Contessa bbk
S23 big valve
Arrow exhaust

When I think I have it jetted right it gets way too rich and fouls the plug out.. currently 32pj/102mj

I backed down to a 100 jet and seems to a lot better and temps stay pretty low granted it’s 70 degrees out now.
