I'm running a 30mm PHBH Dellorto on a 90's era Malossi cylinder. I have a Mikuni fuel pump connected at the Malossi reed valve manifold to provide pressure for the pump, it works fine.
On the by pass line I do not have any restriction. Is there any recommendation on what could be used in the by pass line to provide the appropriate pressure?
Have read the float valve jet should be around 300 would that also be the same for fuel pump carb?
What is the philosophy on float weight? Heavy float or lighter float?
