Carburetor leaking

perryjosh64 · Apr 12, 2022

Folks this is on a 64 Ford 2000 4 cyl gas tractor. Have not run it for about 2 months. Turn gas on at shut off valve and walked around to left side to crank it and had gas steadily dripping out of bottom of carb? Carb is less than year old turned gas off, let it sit for a minute, cranked it then turned gas back on while running and no drip? However when I put throttle to lowest setting where it would normally run fine at idle sounded like it was about to die/stall? Do I got a needle stuck open? Bad gasket? Any ideas?

Float could be sticking or it may have some dirt/rust in the needle seat. Sometime if it is rust you can pull the air cleaner tube off and fire it up and while running at 3/4 or so throttle put your hand over the air intake and try t not flood it out and the extra vacuum will sometimes pull the dirt out of the seat

hummm really,? there is no vacuum at the needle and seat. she is free flow into the bowl and no vacuum in the bowl.

Old or new dirt or any type of trash can make a carb leak. Only hack I know aside from tapping on the carb is to shut the fuel off and run the bowl dry then turn the fuel back on. Sometimes the flow of fuel will dislodge what might be causing the problem. It works better on vehicles with a fuel pump as the pressure helps. beyond that it's time to pull the bowl.

What Old says is in fact true, I've done it also. Think about it: if you run the engine about 3/4 throttle and suddenly totally block off the air intake, what happens? A big slug of gas is introduced into the engine. Where does the gas come from? Um, the carb bowl, right? Sometimes that's enough to dislodge a small piece of dirt or rust.

closing the choke would do the same thing. why not put it to work to get the fuel flowing. but whatever works for you guys.

Update- did the tap on carb thing then cranked tractor, throttled it up and pulled choke for few seconds. No more leak, thanks guys.

I'd say you fixed the symptom but the problem still exists. I'd drain the tank and have a look inside. Then pull th petcock and clean the screen and see what's on it and change/clean the other filters.
