I suspect that is gas, as you do. Do you have the original vacuum operated fuel valve or is it a manual shut-off valve? Hopefully it hasn't filled the crankcase with gasoline over-night?
Is it possible that you had the fuel hose disconnected & some dirt got into the fuel hose and is now jamming the float valve open? Try simply draining the float bowl into a clean glass jar to look for sediment & then turn the fuel valve on or crank the starter to open oem vacuum valve to flush the float valve & bowl.
Might also be good to replace the exhaust header gasket after you get the carb issue sorted out.
