    Water intrusion is always a possibility….But, water intrusion will usually affect idle, I am asssssuming your engine idles normally/fine. Regardless of all the work you have done on your carbs, I am not yet convinced this isn’t fuel system related. Have you done the primer test we have spoken about?
    I surely don’t want you to rip into the powerhead looking for problems before we have ruled out the fuel system.
