48 IDA float level changes

[samotorsport]

So i had set the floats to 5,5 before the last race . Now after redoing the engine , putting everything back together , I rechecked the foats and they where way of . Something like 8-9 mm
My pressure regulator is set to 0,3 bar 4 Psi while the engine is running at idle .
But it does not have a return line to the tank.
So what could have caused this issue ?
Either the priming of the carbs without the engine running ? Or could it be the level changed because it is a trailered racecar where on some occasions the bowls have been empty while transporting ?
Anybody got an idea ?

A tip
 set the pressure at 0.20 (max) bar and 300 in the needle valve
So you do not have problems
At 0.30 bar they want to overflow and the float level wants to go up and down

In this way you can handle 250-260 hp But you must have thick pipes from the tank (12mm -1/2 ")

Thanks for the hint.
I ve got the 300 needlevalves installed.
I only run a 1835 cc , 185 hp and the webers have been modified to have the bigger bowl ,
So in that case 0,2 should work i guess .
I will give it a try , thanks
