Boost FPR trouble

[pork]

Just found out that the standard pressure on my boost FPR is between 5-7 psi, the bike carbs float bowls can't close and flood with fuel,
What can I do?

The bike carbs close at about 2-3 psi, so need another regulator that can go down this far, but also be able to rise in pressure when the boost comes on

Anyone recommend another one?

Il post pic off my one in a sec

This is what I have atm, but the base pressure is to high, is there a way to decrease this, but also allow it to rise accordingly?

Or maybe could I do smithies g to the float bowls

fit a softer spring in the reg neil ?

I took the screw right out,
I've seen other people use a mallory 4309. And they go right down as low as 2 psi. But it's over £100 and can't afford that yet. Which sucks coz apart from that its ready to go


Also almost blinded myself by squirting petrol into my eyes! Smooth!

yeh, but the screw just pushes the spring further tho eh, if you fit a softer spring you will get a lower range of pressures mate

 

[pork]

Aaaah, cool. I shall try and find one that fits
No way off softening existing spring is there?

dunno, carb dashpot springs are pretty soft eh ?
