Hi Bob.

Maybe float...  Adjustment, debris in seat, hanging, or sinking.  You might want to pop the top to see if the float is taking on gas.  Even the soldered floats can pop a leak after 43 years of life.

Subject: <VV> Turbo Carb question



The car is a 66 turbo, recently rebuilt and everything runs quite well.


Tonight I was trying to fine tune the idle and I noticed two odd things.


The engine sped up slightly as I turned the idle mixture screw in. I stopped
at about ¾ of a turn from fully seated.


Also, and I don't know if this is related but as I turned the idle mixture
screw in the gas started to drip out of the carburetor and this is with the
pressure regulator cranked right down to 1 ½ pounds.


The engine sounds fine, is  smooth and idling at about 850 RPM at this
point. The carburetor  was rebuilt and hasn't leaked like this since I put
the pressure regulator in the line.  The engine has about 2,000 miles on it
since the rebuild.  


There are no kinks in the fuel return line and I checked for obvious air
leaks (it was getting dark by now) and all of the connections were tight.


Any ideas or suggestions?
