The Stovebolt Site Forums The Shop Area Engine Shop Fuel Disappears from Carb Bowl over night?

I have a Stromberg BXOV-2 Carb on my 216 and over the last 6 months its been hard to start. While checking the float level I noticed that the fuel level overnight dropped considerably.
Since then I have been starting by cranking 4 -5 times to get the fuel level up then she normally starts OK

My question is where can the fuel in the carb bowl disappear to? No drips or weeping below and I cant see how fuel could go back down the fuel line

Thanks Den

Try a new fuel pump. If fuel pump diaphragm has a hole of crack in it, the fuel will drain back some and siphon fuel out of the carb. Thus the hard start.

Den, I have to agree with both Quindel and carbking. The modern fuel causes these old engines some trouble at cold and hot start-up. Also, I used to have a little trouble starting my truck in the mornings, but after replacing the fuel pump as Quindel suggests, I am able to start the truck without touching the gas pedal. That's even after it has sat for two or three days.
