[Fot] SU HS6 problems during hard braking

[Phil Gott]

Jason;
What sort of Fuel pressure are you running? Should be 1 1/2 to 3 psi, although a Spitfire driver and I run 6 with no apparent ill effect. More than that could be causing you some of this problem.

Now that I'm actually able to brake hard, I'm suffering from what seems to be fuel flooding, possible sloshing in the float bowls and dumping out the jet into the intake...
