Craftsman mower gas leaks into air filter

Craftsman mulcher mower; has started hard in the past. after the 3 hits to prime it would start then die. If you hit the prime button quickly you can keep it running and it gets better. Today when I went to start it, it refused to start. then I noticed gas leaking out the air filter . any ideas?

Carb. float must be stuck open. First if you have no fuel in the tank it must all be in the crankcase.Drain the oil and refill and also check the carb as the float has to be sticking open. Hope this will help you. Donnyb60

SOURCE: toro recycler will run until primed gas is consumed.

The problem is that the gas that sat in the carb all winter glazed it over and gummed it up. Begin by going to any auto parts store, like an aiutozone, and getting a bottle of carb. cleaner. Seafoam is one I use. Add it to your gas, one ounce per gallon of gas. Also, pick up a can of engine starting spray.

Remove the air filter and spray the engine starting spray into the air intake. Pull start the engine and give it additional squirts of engine starting spray until it runs smoothly.

SOURCE: toro personal pace mower 5 yrs old only runs 10-15 seconds.

Was gasoline left in the tank during off season? Sometimes gas will break down and clog the jets in the carb. The priming bypasses the carb so when you put fuel in by pumping the bulb it runs, but dies becasue no additional fuel is coming through the carb after the primed fuel is burned off. Sounds like you need to clean the jets in the carb and in the future, use Stabil in gasoline to keep it from breaking down.

Can't start my mower after replacing fuel filter


Hi Edward: Try this; Remove air filter from carb. Toss in a thimble full of gas. Start. That bit of prime should do it. You may need to repeat. My Craftsman has needed this for cold starts ever since new

I have a new 650 sears craftsman self propelled 22" lawnmower that will not start. I have gone through the prime bulb instructions, still no luck.\r\nAny ideas? Walter in Alberta Canada.


could be the priming bulb gasket between the air-filter assy. and the carb.
I have the same lawnmower and if I prime with gas from a can it will start but stop after a few seconds. When I push the bulb I can hear air leaking in this area. You can replace the gasket by removing the back half of the air-filter assembly. I am looking to buy a gasket today I let you know how it works out! Thanks Ron

My craftsman riding mower model917.274641 won't start. I was using it and when I stopped to put a bagger on it wouldn't start. have replaced plug,gas and air filter. It backfires sometimes when turning...


First, take the air filter off and spray a shot of carb cleaner/ starting fluid in the carb. If it starts for a second and runs on the prime then its a fuel issue. Check fuel filter, fuel delivery, and carb.

Self-Propelled Model Starts, then dies after about 15 seconds


I posted same problem as this couple days ago. Took mower to shop. The governor spring (located just under the air filter) had come off. So glad it was something so minor!

Engin will not stay running dies


No fuel filter but there is the air filter. Try removing the air filter and starting the mower. If this works replace the air filter. If not, then check the engine's carb. Engine was made by Tecumseh. There aren't many parts to a Tecumseh carb so replacing the few parts (gasket around bowl, float, needle and seat) isn't a lot of trouble.

It means that either not enough gas is getting into the engine. The gas you pump in when you prime is enough to start the engine but not to keep it going.


There could be several things that cause this.
1. Old fuel:
Solution: Replace the fuel. Dump out the old stuff. If it is a year old it won;t work.

2. A dirty carburetor:
Solution: Clean the carburetor.
Easy carb clean:
Pull the bowl off and use carb cleaning solution to clean it. (you can buy carb cleaning solution a Wal-Mart in the automotive section. I have also heard acetone will work but I have not tried it.) Make sure not to loose the little parts like the pin.

Better carb clean:
pull the carb off the machine and clean each part with carb cleaner. There is a youtube video someone else posted on how to do this.

3. Your gas/air flow is not adjusted properly.
To check:
Pull off or out the air filter. Try to start it.
Solution:
If the machine runs longer there are two options: The air filter is dirty so replace it, or the air flow is not adjusted proberly. There should be a screw like thing sometimes called the "main jet" that you turn to adjust the air flow. It is on the carburetor side or bottom.
If the machine dies faster or won't start there is probably too much air flow and by removing the filter you added more air. Adjust the "Main Jet" as above.

Hard to start, when it does start only runs for a few seconds.


You need a full tuneup which means after the spark plug you need to do all of these and you will have a good running mower.
Drain gas tank.
Take carburetor off and clean it.
Pull the top off the engine and clean the flywhee maginets and the coil face with a small wire brush of emery cloth.
Clean screen in gas tank if there is one.
Fuel filter if the is one.
Be sure to check for a good spark after all this is done.
If this is all done you should have a good running mower.
