Too much fuel 03 RX-1

[Huntergv]

While running, two of the carbs on my 2003 RX-1 are spewing fuel out the front of the carbs and through the overflow hose. Any idea what may be causing this? Is it the floats in one or both of the carbs?

Sounds like the floats are getting stuck down leaving the needle valve open.

I would start with a thorough carb cleaning. If there is something in the needles, it will wind up in the Pilot jets.

Is it possible that someone recently cleaned the Carbs? It definitely sounds like the floats are stuck down. Is it possible that they were removed and not reinstalled correctly?

I have seen floats that were damaged to the point that fuel penetrated inside the float. Fuel inside the float could keep them down too.
