Getting ready for water

I put a screw in the carb drain, and i need to re-route the carb vents

Put a screw in the carb drain, dielectric grease your plug and all your electrical connections and run all the vent lines ( differentials, carb, fan) to either the headlight pod or up the snorkel

WHAT DOES BLOCKING OFF THE CARB DRAIN TUBE DO? DONT YOU HAVE TO UNSCREW A SCREW TO DRAIN THE FUEL? HOW WOULD WATER GET IN?

I guess some of them have a 1 way valve to sto water from entering the bottom of the carb...Some don't.. Ours always stalled when we got floor board deep and when we put the screw with RTV sealant on it...problem solved....
