How to clean boat carburetor. 1984 35 hp mercury outboard sprays gas out of small hole towards top side of carburetor when starting. Motor will start on occassion for 5-10 seconds, but then gas will spray out of the small hole.

Carburetors are tricky, They have to be completely dismantled, soaked in carb cleaner, make sure all the gunk is off, every jet clean and clear, If you can't get a wire through it, you won't get gas through it, make sure you can blow through it, Get some guitar strings, .009 is about the smallest guitar string you will find, you can buy them separately at the music store if you don't have one. Change the filter in the line, when the carbs go back on, the adj all have to be the same, not one wide open and 2 idleing, Float level is also important, they don't sell complete kits anymore, you have to buy the parts individually, gaskets , etc, good luck.
