On my particular RT I've mounted the gas tank below the carbs so I have a small fuel pump pushing fuel up to the four carbs. Today when I de-winterized it and started it, 3 of the four carbs leaked from the throat.
I'm wondering if the fuel pump pressure is to much for the bikes float valves? I picked a really low pressure model if I remember right it was 3-4PSI, I'm guessing a gravity fed system is like 1-2 PSI?. Its either the carbs valves cant handle it, the valves are shot or my float bowls are dirty.
I emptied the float bowls a few times to clear the junk, One thing I noticed if I run the engine it stops leaking I believe this is because the engine is drinking and one of the valves is always open and relieves the pressure build up. If I just run the fuel pump with the engine off the carbs flood and leak.
I'm sure many here have added a fuel pump and experienced the same problem?
