[FWDLK] Carburetor / fuel Problems

[mrdonr@xxxxxxxxxxx]

While on the carburetor topic, I have a problem that I could use some help with on my New Yorker (440 engine-Carter 4 barrel). It generally starts and runs good but if I let it sit for more than a couple days, it has to pump fuel all the way up from the tank. When this happens I generally just pour gas down the carb to prime it.

 

What would cause the entire carburetor, fuel pump and all the lines to drain? Is this some sort of siphon problem? and is it from the tank or motor? There are no leaks anywhere that I have found. I have considered getting an inline filter with a check valve but I would really like to find out the cause of the problem rather than just temporary fixes. Any suggestions would be appreciated.

 

Thanks,

    With the engine off take off your air cleaner and look down the throat
of the carburetor and manually open the throttle with the linkage and see if
there is a stream of fuel shooting into the throat of the carburetor, if
not, you need to change the cup on the accelerator pump or spread it so it
works properly, that will probably cure your problem.
