What fuel presure should you be running 45 Dellorto carbs at ? Thanks

3 to 5 psi

Seems like a pretty big Spread?

Not really, I aim for 4psi

Thanks Mark I'll try and dial it in at 4

Hey, Paul
What size/jets are you running and what displacement/valve size do you have?
I have a set of 45s sitting in a box and am curious as to set ups that people are using.
Thanks,
btw
I have heard of people doing more pressure to a regulator with a return line to the tank. Somewhat like an FI set up...

The Motors a 2316 not sure on Jet size . I do know so far that a bypass Regulator will not work well with the return line going to the bottom of the fuel Tank. Ask me how I know 1 step foward 5 steps back
