My 11 month old MTD 9.5 hp snow thrower will not get gas.  It wont prime gas into the carb, or get gas while running.  It will start with gas or starting fliud put in the spark plug hole, but will run only 5-10 seconds and die.  I removed the gas from the tank, sprayed through both hoses ( from fuel tank and primer) to clear, inserted new gas, but no luck, .  Any clues?

make sure there is fuel going to the carb (detach fuel line from carb and check for fuel) the float is round and should hang down when the bowl is takin off, the needle is attached to the float by a spring clip, when you move the float up and down that is what controls the fuel in the bowl, so if you take off the bowl and the float is hanging down then there should be fuel coming out, if not then you have a problem from the carb to the tank, u could take the fuel line off the carb and blow air throw it to see if its blocked make sure you take off the fuel cap.

Thanks nipper99 and borat,  the float needle was sticky, I cleaned it and cleaned the seating area around it with a paper clip.  Now it primes up gas fine when pumped.

Put it back together and it fired up.  Thanks again fellas for the carburetor tips,........learned a lot.

Sounds like either you got some bad gas with some crud in it or the tank was sitting partially full for some time without stabilizer.

Glad to hear its now working.

If it doesen't have a fuel shutoff you should really put one on. They only cost a few bucks and can save you a lot of aggravation.. You should shut the valve EACH TIME you use the machine before you put it away. That way if the float sticks or the needle and seat are damaged gas won't be able to keep flowing by gravity and spill out of the carb into your garage. Definitely a fire hazzard not to have a fuel shutoff!!!

have the same problem, check to see if there's a gas filter in the line, mine has one (yard king model). This may be the first place to start.

Hey Guys-

I wanted to let you know that this thread saved me from buying a new leaf blower!  Thanks.  I was about a day away from taking the blower to the junk guy up the street so he could fix it and resell in his front yard. 

It was a daggone sticky float.

Thanks again.
