Carb Drip
Posted: Sat Nov 16, 2013 2:26 pm
There is a steady drip from the "drip hole" at the bottom of the carburetor of my '50 Cub when I open the valve at the sediment bowl. Oh, and it won't start.
(Tank was off for interior cleaning and repaint, sediment bowl has new brass screen and gasket.)
Carb was cleaned and rebuilt with new gaskets, float pivot shaft and float needle valve w/ cage. Needle valve passed the try-to-blow-through-it test. Did NOT replace float, it seemed OK, although I did not try to test it. The drip started almost immediately, didn't seem like enough time for the float to take in gas and not float.
With sediment bowl valve closed, throttle wide open and choke open, it "burbles" when I run the starter, puffs of gray smoke out the exhaust, but it won't catch.
Does the drip mean the float bowl is overflowing, i.e. the float needle valve is not fully closing? Does that mean the float is bad? Or what?? Thanks in advance for your help!
