Most pumps on this type of machine are vacume pumps, they will have a third pipe that connects to the engine ( usually the rocker box ) where it takes a positive and a negative pulse from the engine, if the pipe is not connected or cracked it will not work, the pump itself is normally seale and non servicable, the engine may also have a fuel shut off solinoid in the bottom of the carb float bowl, if this is faulty or is not gettinf a 12 volt feed it will stop fuel to the main jet.

SOURCE: Craftmen tractor w/ Kohler engine stalls out continually

Sounds too lean.
Can you cover the air intake with your hand 90% or use the choke a bit and then load the engine to see if it runs better?
If you ever find a carb with manual high and low mixture adjustments that will fit yours......put it on and keep it on.
You can usually get then from older tractors.

SOURCE: DLT 3000 Intek 18.5 Carb Float Stuck?

If it starts cold and runs for 10 min then it sounds like the fuel cap is not venting properly, try runnin engine with fuel cap loose and see if it dies. 9 times out of 10 the fuel cap is the culprit. Let me know

Sounds like you may have a problem with Choke adjustment, or perhaps a broken choke cable. Do you have a workshop manual?

SOURCE: tractor fires off with starting

Obviously, you are running out of diesel supply from the supply tank.
1. check to see the level of gasoline, acquire some more when necessary to be refueled.
2. Give the ignition another spark, should power on.

consider how the power button is turned on. The kind of engine could require several switches before the engine powers on completely.

The engine is not expected to malfunction without any external situations causing damage. For an engine situation, could be due to storage for extensive periods after usage. For diesel engines of very economic engines, would require several ignition attempts to ignite after storage the equipemtn for a while.

Mean while, check to see if all fluid are in proper quantities, than power on once more after performing fluid top ups.

Note; consult the previous operator of the device. Possible solution the problem could be made available.

Consult a technitian if possible.

SOURCE: I have a j.d. 345 lawn tractor with 20 h.p.

It sounds like you have a stuck valve on the carb. I recommend taking the carb off, taking it apart and cleaning everything well with carb cleaner. When you remove the lower bulb on the carb there will be a float valve inside. Check the tiny needle valve for any residue. If it still looks bad (the valve) after cleaning you may need to replace it.

Usually a good cleaning once every year or two will take care of any carb problems.

Lawn tractor troubleshooting

More than likely this tractor has a diaphragm fuel pump. The only way of testing these kinds of pumps is to take them apart and make sure the diaphragm is not tore.

Simplicity lawn tractor problem

Check your fuel cap. If not venting properly, gas can be forced to places it shouldn't be. I also agree with carb over haul. If alot of gas in oil & alot of gas outta exhaust, lean towards carb issue.

Hi It is almost impossible to get my 86 1.6L Nova to start after being shut off for several hours (overnight) I put a new fuel pump & filter on which didn't help then put an electric pump on. Still...

Under hood fuel lines, touching coolant or heater hoses.
Fuel lines under vehicle close to or not shielded from exhaust pipe, converter, muffler. Fuel lines pinched or crushed.
Fuel filter changed recently.
Fuel pump pressure. Fuel pressure regulator & Fuel pressure sensor.

The age of your vehicle also guarantee's a vacuum leak. It may sound silly but the truth is rubber grommets, and hose's shrink and dry out over time and the harsh environment under the hood makes it worse. Check all vacuum lines and fittings attached to the intake manifold, valve covers (pcv valve), and be sure to check for a vacuum fitting on top of the intake just behind the throttle body. Does it fit tight in the hole? You can seal loose fittings with a high-temp RTV (Red) silicone sealant/adhesive. Several small leaks add up and your engine, heat/AC, and transmission will be all to glad to tell you about it.

Aside from that, if you are still having problems, Have a look at the MAP & Oxygen sensors. Finally, you may end up replacing the TBI throttle body assembly.

My weedeater will only run a short time in the full choke position-when I move it from full to half --it dies--almost like it isn't getting enough feul--I also notice the bulb on top the carb...

The bulb will function when not completely full. It really never is as it has the job of moving old fuel/air out of the carburetor and back into the main fuel tank. Hence, the air pocket inside it.
The problem you are having is quite common and could be caused by different things. An out-of adjustment carb acts this way. A dirty carb acts this way. A carb in need of a gasket/diaphragm kit acts this way. If you don't know these machines, diagnosing and curing this problem is difficult. It is fuel related though as you suspect. I say, try adjusting the carburetor (I will include a link) and if that doesn't fix the problem, then install a new gasket and diaphragm kit (not expensive).

When i give it some throttol it dies out.79 sporty 1000cc with cv carb.could it be fuel or timing

If the engine is running, it's not a timing issue. If the engine is running and the timing is not right, it would continue to run when you give it some throttle but maybe not run well. I'd suspect the carb. If you've put a later model Keihin CV carb on the bike and it dies when you give it throttle, you could have either a bad accelerator pump diaphragm or a hole in the vacuum diaphragm that controls the slide. To check the accelerator pump, remove the air filter so that you can see inside the mouth of the carb. With the engine OFF, crank the throttle to wide open. Watch for a stream of fuel to squirt out of the brass nozzle just inside of the mouth of the carb. If you do not see the shot of fuel, your accelerator pump in not working. You need to drop the float bowl off the carb and check the diaphragm and fuel passages to make sure they're open. To check the slide vacuum diaphragm, with the air filter off and the engine running, rev the engine up a bit and watch the slide in the carb. It should move up and down. Do not get your face too close to the carb. If it spits back through the carb, it could cause you some injury. If the slide does not move up and down, you may have a hole in the vacuum diaphragm. In order for you to install the Keihin CV carb on this model Sportster you had to have changed the intake to one specially made for this installation or you had to use an adaptor. Make absolutely sure you have no vacuum leaks. Look on the backside of the carb for a vacuum port that you may not have connected to the VOES switch.

Good Luck

17 HP briggs & stratton not getting fuel

First change the fuel filter. Carefully pressurize the fuel tank to see if you have fuel flow to the carb. If no luck, depending on the yr. You may need to rebuild the fuel pump which is on the front of the carb and some models its on the side of the blower housing. This is not as easy as it sounds. I accidentally put one back together WRONG and destroyed it and I have 35 yrs experience at this stuff. I had to order a new pump body from briggs.
The diaphragm kit is part #693503 is for the 4 screw fuel pump and includes everything you need to completely rebuild the carb and fuel pump.

Fuel starvation - 'lean fuel' condition
Basic things to check:
1) spark plug
2) spark arrestor in muffler
3) fuel lines and tank filter
4) turn adjustment needles out (counterclockwise) 1/4 to 1/2 turn
Chain Saws:
5) check impulse tube and intake boot for cracks or leaks
*if all of the above are OK and/or do not improve performance then:
Remove Carburetor
6) replace gaskets/diaphragms
a) use a spray carb cleaner to clean jets, holes, and body of carb
b) fuel pump diaphragm goes against the carb body,
then the gasket towards the outside
c) metering gasket goes against the carb body,
and the diaphragm goes towards the outside
