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
