Good day to you,
First of all if the water pump hasn't been changed out then I would defintiely do the water pump replacement and also if the carbs haven't been rebuilt I would rebuild those also especailly if there flodding the engine sounds to me the needle and seats in the carbs are worn out and that is what is causing the flodding problem with fuel. Someone on this forum will chime in with more experience and let you know but that is what I am thinking is going on. Take care, Bob
