When rebuilding an old BRIGGS float type FLO JET carburetor, is there anything special to look for? I let an engine set up for a while, and the old gas gummed up the carburetor. I tried rebuilding the carb, but apparently the needle is not seating properly. Gas pours out of the carb. I have checked everything, and cannot find the problem. The float seems to be good when I check it, and everything seems to move freely when the float and needle are assembled. I have checked the float level, and it seems right.

Any suggestions?

Aloha, Assuming that you have the correct needle and seat, adjustment, I would take another look at the float. Is it brass or the plastic type? Sometimes the brass type will spring a leak and the plastic type will absorb the fuel making it heavy.

Brass float. I've tested it for leaks, and can't find any. It floats very well out of the carb.

Aloha, When you said that you rebuilt the carb, did you get a repair kit and change parts or did you just clean out the carb. If you added parts from a rebuild kit like needle & seat, be sure it matches the old one. How did you check the adjustment of the float?? Did you do it by eyeballing it or with a float gauge?? Did you adjust the float?

Mahalo,

Used a genuine Briggs carb rebuild kit. Seat is a pressed in brass insert. Used the VITON tipped needle included in the kit, and cleaned the old seat with carburetor cleaner. Adjusted the float by eye, level from side to side, and front to rear.

I think that the menehunes have put a curse on it.

Aloha, Yeah, there could be a curse on that carb. LOL Usually the float arm has a v notch where it should be bent to adjust. So if you didn't do any bending something must have changed. You could try bending the float arm in the direction that lessens the fuel in the bowl. The reason I am saying this is because some floats are attached to the top cover and some are attached to the bowl and I don't know which may apply to yours.

Thanks for trying to help. The float attaches to the top of the carburetor. I tried adjusting the float so that it would shut off the fuel quicker. That didn't work.

With the bowl off the carb, and the carb hooked up to a fuel tank, you can hold the float up with your finger, and the fuel shuts off like it should. I keep wondering if the float is hanging up somehow, inside the carburetor.

Aloha, Is the needle valve horizontal or vertical?? Is it possible to post a picture of the float attached to the top?

The needle is vertical, straight up and down. The float is attached to the top of the carb by hinge pin. The needle sits on a tab on the top of the float.

Sorry, I can't post a picture.

Aloha, Where is the fuel pouring out from?? At this stage, I would find a fitting and a short length of hose and attach it to the fuel inlet. Then gently turn the carb upside down and blow into the hose. No air should pass because the needle should be snug against the seat. If it's ok, then the float system should be working ok. Do it a couple of times and turn it over gently so if it is binding, it should show up when you blow into the hose. Did you have any left over parts after the overhaul??

The fuel is dripping from the carb at the air inlet. The only leftover parts were ones which gave you two choices. There were two needles in the kit. One VITON tipped needle for a carb like mine, with the pressed in brass seat. One solid metal needle, with corresponding rubber seat, for the other style carb.

Thanks for the idea of blowing through a fuel line. I will try that this weekend, and let you know what happens.

Which island are you on?

Most likely cause of a carb dripping is the inlet needle and seat. The float valve seat where the needle goes in must be flush with the surface or it will not shut off the gas causing it to leak. How the needle is hung from the float may also affect it, the wire clip that connects the float needle to the float, the open end of the wire that hangs from the float must aim towards the air intake or air filter side of the carb. If it's pointing toward the engine side, the needle won't center correctly and may leak. Another thing that can cause it is leaking of the nozzle behind the main jet. Pressure check the float valve before reinstalling the carb. The problem may be the nozzle above the main jet there is a flange that looks like the face on an engine valve. This seals to the carb casting. If it leaks the gas runs from the float bowl into the intake of the carb. The float valve will keep letting it in as long as this lets it run out. It has some small Teflon washers that will slip over the nozzle and hopefully seal it. If your float valve pressure tests OK This is a likely suspect. Finally, bitting down on the left corner of your bottom lip while you assemble it may work. Have fun

Aloha, I am on the island of Oahu, and where are you located? Yeah, let me know what what you find.
