Just got the new dual weber kit (40 IDF) and it's all in. Presure regulator, fuel pump, it's all in (have not started it yet) but I have a problem. One of the ports is loading up with fuel. I pulled the top and the float was working (the other port was not emitting fuel after the float reached the top. Took drivers side carb off. Setup on the trunk lid with lot's of towels and turned the key on. Like I said all the other three ports stop however this one keeps dripping fuel. I am lost and not knowing exactly what these screws do (other than the idle) I really am scared to start turning them. Why would one port emmit fuel and not the other when they share the float?
Any suggestions guys? |

I also suspect a bad casting. Fuel should only flow from those ports when the engine is running and there is a vacuum on the ports (butterfly in transition from idle to mains). You are talking about the little holes just above the butterfly when it is closed? If thats where it's coming from I would return them.
Improper float adjustment will cause fuel to flow out of the mains with the engine off and the pump running. |
