Ford 9n Leaky Carburetur

Winston9n · Jul 30, 2021

Hello All,

I have a ford 9n, and when I turn on the gas line a bunch of it comes leaking from the choke rod/linkage that is attached to the carburetor. Any ideas why this might be? I appreciate the help.

Most likely float valve not closing....float bad or binding or bad needle/seat or trash in same.

As jmor said, your carb is overflowing because fuel has not shut off. It should be draining out the bottom of the carb though, but that may be plugged.

Following is a copy of some info I posted in the thread: TXS33 Carb has no Sintered Material in Bowl Bottom

[i:ea1367ed9d]Should not be any fuel in that area of the bowl unless the needle valve doesn't seat, and the carb is overflowing with fuel. That's why that drain is there, to allow excess fuel a way out before rising to the level of the mouth of the carb and coming out there. If it did reach that level, and your air cleaner hose connection was tight (as it should be), fuel would rise up through the air cleaner tube eventually reaching the manifold height and any open valve, and get into those cylinders.[/i:ea1367ed9d]

Winston,

Great News - this is THE ideal time to teach yourself how to rebuild that 9N carb (as many thousands have done before you.)

THOROUGHLY clean every bit of it's insides, blow out all the now clean passages and replace (from a rebuild kit) all the worn or worn out 'expendable' components. Simply follow instructions.

Adjusting the now perfect carb is outlined in the Ford 9/8/2 N repair manual (referenced many hundreds of times here). Many youtube videos for first timers are available as well. A side benefit is that a meticulous rebuild returns the carb to its original specs - AND, think about it, you won't have to shut off the fuel tank when you park it. ((Do you shut off the fuel tank of your pickup truck every time you park it - HECK no!!!) That's a """trick""" that owners who can't get the carb working right pass around among themselves.

The good news - steady, meticulously clean and detailed work will make the process not hard at all - and in the end you can advise others on the process with stories of your own.

Thank you to everyone! The float was stuck. I was able to take it apart and clean it a little. It's working just fine now.
