Needle valve sizing.

[v8ian]

I have a c20xe on 45DCOEs soft cams @ about190hp, the carbs have started dribbling fuel out of the trumpets when idling and when the engine is shut off, my first guess is float levels, as I need to keep the car mobile, im not keen on pulling the lids off the carbs to ID the float valve which I want to change too,
Whats the consensus on the size For the float valve, I would guess 175s, would be big enough? Obviously the fuel pressure will need a check over too,

Was it okay and started it dribbling fuel?
Check for leaking (punctured) float and also that the float valve moves freely as it can get stuck if the float is allowed to go down more than it should (bent tab).
I always put 200 float valve in, but 175's should be okay for you.

175 is plenty big enough
