Vacuum readings???

[Rampton]

Hi all does anyone know what the vacuum reading on #2 carb should be on a cb750 Dohc 1981 I'm getting 8 cmhg. Kind regards Rampton

Synchronised carbs to number two @ 5cmhg and running fine, fitted new rubber boots airbox to carbs and carb to head, so think I answered my own question in the end.rampton

Yes there is no set number, adjust to number two like you did
