Re: Fuel Leaking out of Carb, Squirting out of main nozzle....
jason
the particular carbs in this disscussion have no bowl vents,even if they did a clogged bowl vent makes the needle leak as the air pressure above the float prevents the float from rising thus causing a needle leak.
this carb is more similar to the backdraft carb and uses very large main air jets that hold NO fuel to clog, unless they sink or bugs make nests they just dont clog.
occasionally I will soak a stripped fuel bowl but I havent soak an outboard carb body in over 20 years.
I use CRC-06064 spray and or combustion chamber cleaner.
I do have some very fine wire drills and will use strands of copper wire to clear bowl passages.
goes back to what I said,the only cause of fuel leaking out of the emulsion tube is a leaking needle.
why it leaks I am not there to see.
beauty about the V4, 2.6L v6 carb design using the twin floats is the needles,pilot air circuit,main air circuits are all above the liquid level and rarely clog due to sitting.
sinking is a different story.come to think of it last week I did the carbs on an F100,a s150 and a 94 V4.
also got to do the VST and fuel system on a Z300.
gotta love E-10 fuels.
keeps my horse in hay and makes for a merry Christmas.
what the above poster is NOW describing is a lack of fuel in the fuel bowl or he isnt using the choke correctly.
now we gotta find out why.
either the quick connect is blocked,the filter is blocked both carbs have all 4 needles blocked or all four floats are incorrectly set.
remember he is posting now about it will run if a flammable gas is introduced seperatly from the carbs and will run until the combustables are gone.
shows me a lack of fuel in the intake and clyinders.
goes back to what I keep preaching, you MUST understand what each subsystem does and how it can affect the rest of the subsystems in a system.
that and Suck,Squeeze,Bang and Blow.
if all 4 are present it simply runs as designed,if it does not run as desiged figgue out which of the 4 is missing.
