12.5 v twin , new fuel pump and filter. Cleaned carburetor Starts and runs as long as you pour gas into carburetor. will not run otherwise.

Open the gas cap, remove the fuel line from the carburetor and use compressed air to blow the line clear. Having done what you have already if the line was clear, you would have gas to the carburetor.

How do I fix a Craftsman lawn mower that starts but soon quits running?

Your problem is the carburetor. Anytime your equipment runs and shuts right off, you can automatically eliminate spark and air. What you have to do is take the carburetor off and remove the bottom bowl, get carburetor spray from advanced auto, gum out,... Spray into every port in the carburetor, every hole you see, in the direct middle 9f the carburetor is the emulsion tube, spray in there as well. If you have an air compressor, that will help too, blow these holes out. Use 89 octane gas from now on as it's cleaner gas...

If you need more visual ...go to you tube, type in how to clean mower carburetor, you will find many videos... you can do this job yourself...

Troubleshooting chainsaw

Chain saw and other small engines are particularly susceptible to problems caused by stale fuel containing ethanol. Always use ethanol free fuel or add a fuel stabilizer if the saw will sit for more than a month. If you spray engine starter (ether) in the carburetor and it runs briefly, the carburetor is probably gummed up. You can possibly rebuild the carburetor, but you need the precise model of rebuild kit matched to the number on the carburetor. It's often more cost efficient to replace the carburetor, an easy job. Stihl and other manufacturers have so much trouble with this issue, that they have dropped the price of replacement carburetors to about $50.

Another way to avoid this problem in the future is to drain the gas tank and run the saw until the carburetor is completely empty before storing it.

A less likely problem is a clogged muffler if you have been running a fuel mixture with too much oil or an inferior brand of oil.

Will not start when hot

Hi William
When your engine quits after it gets hot,
You either have a problem with gas flow being restricted into the engine or with the spark.
This is a common occurrence on older-model engines.
By replacing your spark plugs and keeping your gas lines clear you can reduce the chances of this problem recurring.
Possible Vapor Lock:
Vapor lock happens when excessive heat and vapors build up in the gas tank and aren't vented properly.
Check for this problem the next time your engine dies when it's hot.
Unscrew the gas cap, vent the gasses and try to restart your engine.
If it starts you have vapor lock, and will need to carefully inspect the fuel tank's vent hole to see if it is plugged or damaged.
Clean this hole with a brush and rag.

Possible Ignition Problems:
Acommon problem is an old or dirty spark plug. When the plug gets covered in black carbon the spark will have difficulty firing, especially when hot.
You may also have a problem in the ignition module or the coil in the module.
Again, run the engine until it quits and then squirt a little starter fluid into the open choke valve, underneath the air filter.
If it starts up you likely have a fuel system problem, but if it doesn't start, your ignition module or coil is likely almost finished.
Fuel Supply:
At certain times when the engine gets hot, the flow of fuel to the carburetor can get restricted.
This can occur with a dirty fuel filter.
The hose itself, when hot, can also lose its proper seal to the carburetor, restricting the flow.
Replace your fuel filter and hoses on a regular basis, usually once a season.
Try adjusting your carburetor's screws to see if you can richen the fuel mixture in the carburetor.
Other Problems:
A dirty or worn-out carburetor can also cause similar problems when hot.
You should get your carburetor cleaned and serviced.
Try installing a carb kit to older carburetors to help with the flow of fuel.
A fuel pump inside the carburetor can also start failing and any warping in the diaphragms will also cause similar problems.
You can check for a dirty carburetor by squirting a shot of carb cleaner into the open choke hole just after starting the engine.
If you see a lot of thick, dark smoke pouring out the muffler, your carburetor is dirty.

I have no fuel at spark plug on my honda generator ex1000, i have cleaned carb and spark plug,

Make sure you have flow from the tank to the carburetor. Also, when you cleaned the carburetor, there are several jets that have to be open in order for the fuel to "flow" through the carburetor. The carburetor on this generator has a pilot jet located on the top side of the carburetor and a main metering jet that screws into the very bottom of the carburetor and will be visible when the bowl is removed. After the main jet is removed there is a main nozzle that also has holes in it that have to be open also.

Another problem that is possible is compression. If the engine does not have sufficient compression it will not "pull" the fuel into the combustion chamber on the intake stroke. Hope this helps to get you in the right direction.

I have an hesitation when the car accelerate

I'd have to disagree with this. I don't think there's anything wrong with your carburetor. Myself and my very close friend both have a 2009 A4 and both have the same exact problem. We've reported it to the dealer and they said that over time it should go away. They say it's because the car has a transmission that learns your way of driving. I've had it since July of 09 and it still does it, but I'm used to it now.
