Hi ehoff7462987...
Your inlet needle valve is stuck open, or has trash/debris under the needle seat allowing the fuel float to be jammed open and allowing the fuel to flow out of the overlflow of the carburetor.
Here are some suggestions.
--------------------------------------------------------------------------------------------------------------------------------------------
Try to tap the carburetor bowl lightly with a plastic faced/brass hammer to loosen the float valve and it may solve your problem.
If the mower/weedeater is over a year old, then I recommend that you buy and install a new carburetor repair kit,because the diaphragm will get hard and that will cause it to be hard to crank.
Sounds like you will need to clean the carburetor or replace your carburetor internal rubber parts like the diaphgram and O rings.
Be sure to use compressed air to blow out all the fuel and air passages.
Be careful when blowing out the passages, because there are sometimes small rubber type seats in the bottom of some of the passages.
Sometimes you can get by with priming the carburetor or using starting fluid and letting it run a few times like that and it will flush the gunk out of the jets,but most of the time you will need to rebuild the carburetor.
Keep in mind that the float for the carburetor must be level when you go to reassemble the carburetor or follow the instrucitons you get with the carburetor kit.
When you clean your carburetor and remove the jet screws, you will first need to lightly seat the jet screws.
But before you lightly seat the jet screws count the number of turns it takes to seat the jet screws from their original position.
Be sure to mark the turns down on a piece of paper.
That way when you put the jets back in, you know to lightly seat them first and then turn them back out to their orginal position before you started.

Troy-bilt 34322 343220110815 mower will not start

Dump out old gas. Fill with fresh gas. Always use Stabile in gas. Clean or replace park plug and air filter. Check oil level. All mowers have a low oil start cutoff. 30w oil. If any grey in oil moisture contaminated, dump out old oil and refill. Check fuel line for cracks or leaking. Check primer bulb for cracks, replace if required. Clean outside of carb with carb cleaner to ensure easy choke operation. Remove carb bowl from carb, ensure float hangs down freely. float down fuel flow, float up fuel flow stops. Check bowl screw for hole thru bolt, if so clean out hole.

I have a honda tiller that I have checked and it is getting fuel to the carburator and has good spark but will not continue to run. I can get it to turn over by spaying carburator cleaner in the carburator...

You will need to remove the float bowl from the carb and clean out the jetting. There are small tubes that serve as a restriction for the amount of fuel allowed to enter the engine. These can easily be plugged up with particles and grime after sitting for extended periods. Also make sure the adjustment needles are not screwed down all the way. This, in some carbs, will completely cut all fuel.

First, the primer/purge bulb does NOT have to fill completely to function. It's purpose is to remove old fue and AIR from the fuel system (carb) and move it back into the fuel tank. You normally will have an air pocket in the bulb. An air leak in the fuel system or loose carburetor screws or fuel lines in the wrong location can cause your problem. Check the fuel line and fuel filter for a good connection in the fuel tank. Remove the fuel pump cover on the carb and make sure the very small, round, wire mesh filter is not clogged with debris. When old fuel lines deteriorate, they crumble and if the filter is broken off, the fuel line to the carb will ingest bits and pieces of old fuel line. Check all these things and post back.Sometimes, if the bulb is on the carb, a check valve in the carb can stick. When you check the condition of the mesh filter inside the carb (opposite the side with the vent hole), then liberally spray with WD 40. Strong solvents and cleaners can SWELL up the tiny check valves in the carb, causing problems. So you see, it is hard to pinpoint exactly what happened without some removal of parts and diagnosis.

Hi i have replaced my primer bulb and now the fuel will not pump into the new one. What else is the problem?

Check the condition of your fuel filter in the fuel tank and the fuel lines themselves. When lines get old, they become flaky and bits of them deteriorate from the inside out. These small bits can clog the fuel ports and check valves in the carburetor. Make sure the fuel lines are clear. Your carburetor has a small screen filter inside of it to collect debris such as this. It is located under the pump cover. That is the side of the carb, opposite the side with the vent hole in the cover. You can try spraying carb/choke cleaner aerosol spray thru the fuel lines or pull them off of the carburetor itself and spray the inlet and outlet ports of the carb. This is done in lieu of removing and inspecting and cleaning the carburetor.

My Honda fg100 tiller started right up. The problem is the engine dies when I started to till. I cannot get it to run. What do u think is wrong?

Pull off the float bowl. Clean the bowl and bowl nut. Also in the threaded are where the bowl nut screws in there is a fuel jet / orifice with a tiny pin hole in it. If you have a inlMake sure that pin hole is clear of debris. Pull off the hose going to the carb and make sure you have good fuel flow to the fuel manifold. If you have poor fuel flow check the in line filter and the fuel tank exit port for debris. Use carb cleaner to clean fuel passages. With the float bowl remove the the main fuel line disconnected shoot carb cleaner from the float needle to the fuel hose connection and then from the fuel hose connection to the float needle. Reinstall the main fuel hose, float bowl and nut. Check for leaks BEFORE switching on the ignition.

Additionally make sure the engine Oil is serviced correctly. There is a low oil sensor that will kill the ignition if the oil level is low. For trouble shooting only you can disconnect ONE wire and check spark. If you did not have spark with the oil sensor connected and you have spark with it disconnected then the oil level sensor is either working correctly sensing a low oil lovel or... it is dirty and needs cleaned.

This SHOULD get you up and running again. If not just respond here with your ENGINE number and I will help you

Troy bilt mower ran fine then died and now it wont start back. It has fire and a new spark plug. It gets fuel past the filter. It starts if i put a small amount of gas into the intake. Whats wrong? My...

Remove the air filter and set aside.
Take a can of carburetor cleaner and spray the inside of the carburetor.
Let it set for a moment and then try starting the engine. It should run a few seconds. Repeat. When it starts squirt a small shot of cleaner in the carburetor to keep it running. That should remove the varnish the gas leaves as it evaporates over the winter.

If it still won't keep running then there is trash in the float bowl plugging the needle valve seat and the jets.

1) Turn off the gas or remove the gas line and plug it with a small screw or stick to keep it from leaking out of the gas tank.
2) Look on the bottom of the bowl for a nut .
3) Remove the nut and drop the float bowl.
4) Carefully remove the pin holding the float and needle valve assembly.
5) Take the carburetor cleaner with the straw it comes with and spray every hole in the carburetor to clean the jets . (up through the needle valve seat, down top of the carburetor , see a hole, spray it with the cleaner.)
6) Clean the float bowl.
7) Reassemble and make sure the gas isn't leaking and try to start it again.

Carburetor is leaking through a small pin hole, this hole was made by manufacturer

the "hole" is an atmosphere vent, what is happening is the needle that shuts off the fuel to the carb when the bowl is full is not working properly, depending on model the carb repair kit that is most used to repair plastic tubed carbs is 632760b .....also be sure to flush out tank and fuel lines before adding fresh 89 octane fuel to the fuel system....hope this helps

Fuel Leak from the Carburetor

Remove the water trap bowl at the bottom of the petcock, (gas valve). Is there any water or trash in the bowl? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There should be a screw on the lower side of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.

Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Check the float as they can go bad and fill with gas such that they no longer float. Remove the idle screw and the air screw on the outside throat of the
carb and spray into the screw holes as well.
< < READ CLOSELY > >
Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the
carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. The idle speed will probably different so adjust the idle screw to get back to where it was. This process should get you back on the road.
