Ok new at fixing boat motors changed distributor because wouldn't spark it worked and the thing runs now but have new problem fule is pooring out of bottom carb after running for 10 seconds and floods out should i rebuild fule pump and see if that fixes the problem or should i do both fule pump and carbs all at once since i cant find anyone that is willing to fix since the motor is so old..

Normally a flooding carb is due to a bad inlet needle and seat, a bad float or a bad adjustment or some combination of all three. Recommend cleaning and rebuilding the carbs with new gaskets. Inspect the floats and inlet needle and seats, and replace the ones that are worn or deterioated. Readjust float height as specified by the service manual.

Those were notorious for bad or stuck floats.
