oil don't Boom as good as fuel it just don't. the semi synthetic will give it better ware protection, to much and i'm thinkin she stick the rings, compression

Detroit Whitey , said, cool cans are leagle in x class

have you ever seen a hull with a dry ice can go through inspection after the race, and pass, and or not get DQed for the "can", just askin.

why does fuel psi not drop at the carb? cuzz it can just free flow back to the tank, does the 5/16's line back the volume up so it run's to the carbs as well?

He's got a 060" jet in a fitting to make a restrictor on the return side.
Condolences for you re your step Mum

[Fast Fred]

thanks guys, got to talk to a B-17 pilot today, that was cool.

my return set up is vary similar to the drawing, why do see it pullin air bubbles?

it's all 3/8'th line, the reg has one "in" and two "outs", one out has a big pin, it chokes off the return line to set 3 and a 1/2 psi to the carbs, total available fuel
some thin like 84GPH, something like that. what pump are yous runnin?

[850cc racer]

Hey Fred sorry to hear about your step Mom


you have to put restriction in the line straight after the last carb. as per the diagram. otherwise it does free flow

i have two restrictors to allow build up in the T fitting for the choke.

how do you have the fuel set up?

i MAY be able to take a little picture of my fuel so you can see how ive done it.
