Mercruiser 898 with 2 BBL carb.
After sitting about a week I need to run the starter longer than I am comfortable with to get fuel back into the carb. Maybe about 5-10 seconds. The engine will fire up almost instantly when I pump the throttle once, but it almost immediately dies since there seems to be no fuel in the carb bowl after that one squirt from the accelerator pump. I don't know if the fuel is evaporating or flowing back through the lines and into the tank. There is no evidence of a leak anywhere. What should I look for to resolve this problem? An old check valve in the fuel pump? I have a spare fuel pump if this is the case.
I've read somewhere that some carbs are more prone to this problem than others and the only sure fire way to resolve this problem is to install an electric fuel pump.
