There is spring that is for the float. The float pin runs through it and some how keeps the float from bouncing. I can't find anything that shows how it connects the carb. body or float to work properly.

Re: Float spring on tecumseh Carb.
Ok, that pin is the needle valve. It should move freely, and the spring should attach it to the float. When the carburetor bowl is full, the float pushes that pin up to shut off the gas flowing into it. Otherwise, it would continue to dump fuel into it until it overflows, and you would have gas all over. The engine draws gas through the jet in the bottom of sump that you see sticking into the bottom of the bowl(this likes to get plugged up and keep your engine from running) The spring just kind of sits in there so that if the float moves, it will pull down the pin as it moves.

Hi Stan,It sounds like you are missing your float needle. There is no reasonable explanation for it to disappear if the float was not removed.The float needle is typically made from aluminum with a black conical gasket tip to create the seal when the float is in the raised position to stop the flow of fuel. They are fairly inexpensive to replace. Seeing that your generator is a Powermate 5000, if it is an older unit using a Tecumseh engine you will have to be very specific with serial and model numbers, since Tecumseh has gone out of business. Replacing the float needle is fairly easy. Some carburetor bowls are formed with an uneven bottom to allow proper travel of the float and they must be re-installed in the correct orientation. If the bowl is round and completely flat on the bottom the orientation doesn't matter. After the bowl is removed the float needs to be removed also. Where the float hangs on its hinge there is a stainless steel pin that needs to be removed, some carburetors have a nub on one side that allows the pin to be removed in only one direction. A finishing nail that is smaller than the pin will push it out with little effort. On the top of the float as it would be oriented in its installed position there will be a horse shoe shaped receiver that the float needle slides into, there also might be a small spring in the replacement, be careful with this spring it is easily damaged and easily lost. The float needle is placed into the receiver on the float, then carefully take the assembly and slide the float needle into the orifice while the float is lined up to go back into its hinge. Align the float to receive the hinge pin and slide it in. Make sure that your bowl gasket is in good condition and replace the bowl keeping in mind if the bowl is formed for float swing travel. Add a little gas and check for leaks. If leaks are present the causes will be bad gaskets either on the top of the bowl or the bottom by the nut. Another cause could be that the bowl is rubbing on the float and keeping the valve open, loosen the nut and rotate the bowl until the float swings freely then re-tighten and check for leaks. Last but not least you have the wrong float needle and it is not long enough to seal correctly when the float has risen to the full position. Good Luck,Michael Burke
Yes the problem with the mower not running is the little spring you talked about is missing from under the float arm of the carburetor. It is necessary for the mower to run right.
The little spring inside of the carburetor goes under the float arm. That is where your fuel inlet needle/float valve is located...on the arm at the end. Normally there is a small indetion in the carburetor base and a small protrusion on the underneath of the float arm where the spring will be in the right postion for installation. The spring will set in the indention and you will install the float arm with the needle/float valve and float rod into position over top of the spring,you will push down until it is in position and then you can tighten the screw that holds the float arm assembly in position. Your carburetor should be working properly to run now as long as you do not have other problems in the fuel system or electrical problems.

You have some debris in the float needle valve. It will require that you remove the float bowl and the float. To remove the float you will need to remove the float pin and drop the float straight down. The float needle will come out with the float assy. Then take some carb cleaner or compressed air and shoot into the float needle chamber to clear the debris.
Check the float needle tip for any rough spots. It should be smooth. The reinstall the float needle and float assy making sure to note the float pin position is the same as originally installed.
Last check before installing the float bowl. With gas available to the carb lift the float GENTLY to the level position. Fuel flow should stop. If it does not stop then there is still a problem with the float needle or the needle seat is damaged and will have to be replaced. The needle and seat are in the same package if you purchase a replacement. The seat can be difficult to get out of the tiny hole. A really hard piece of wire with a mini 90 bend on the end will often do the trick.
If for any reason you have to remove the carb.. do yourself a favor and take PICTURES of the linkages and spring(s) so that you can re-install them correctly.
If you need more assistance please pass me just the ENGINE number so I can pass you the diagrams with part numbers if necessary.
the spring is just to hold the needle in place, it just hangs there, I would suggest you check the float for seepage, if its one of the older metal ones its likely leaging gas into it and sinking, causing your flooding situation. Something else to sheck is that you have theseat installed correctly, Remember the ridges on the seat piont away from the needle. and remeber to set the float hight level..
By pin I am guessing you are describing the needle? Some carbs have a small tang on the float that connects the needle to the float with a small wire spring while others just push against each other. I would take the carb off the engine and hook up a fuel hose with a small bottle that is higher than the carb and with the bowl off manipulate the float up and down and be sure the fuel flows freely when the float drops and frees the needle. If this does not happen-try more cleaning but a new carb may be necessary.
