2011 - model # 247889571 - SEARS CRAFTSMAN 24" SNOWBLOWER - 179cc OHV There is fuel in the carberator bowl but it doesn't make it to the engine.

I pulled the plug and poured some fuel in the cylinder and it fired but quit.

I know it simply not getting fuel from the bowl.


Does the primer belows fill with fuel and get harder to push when fully primed?



Is it complicated to free up a stuck fuel float?


Any other possible causes?


Thanks

Wade,
Is it possible for me to get a larger copy of the instructions for getting to the carburetor, I can't read it??

Briggs and Stratton sent me the link below for one of their products (a fuel stabilizer). In the advertizement they show photos of what water can do to a carburetor and how gas with Ethanol can cause water to build in the tank. They also state the same 30day time period that Pennzoil informed me of.

I'm not trying to harp on this subject or single you out by any means. I just got the email from Briggs and this thread was just still fresh on my mind.

See the link I've attached for more information regarding gasoline breaking down. The gas we have today is not the same stuff we had 20 years ago. With ethanol blends all over the place now, it just doesn't store like it used to.
Obviously, how it's stored can have a lot to do with that. If you store gas in a plastic can that's completely full and sealed air tight, it will keep for quite a while. If it's not completely air tight then it's not going to last as long. If the container is not full it will last even less time. There are fuel conditioners (like Sta-Bil) that can be added to the fuel that help prevent the fuel from breaking down.

There is also differences in fuel systems that come into play. Some carburetors are not as sensitive as others. The carburetor on your snow blower engine is one that just doesn't deal well with contaminated gas.

For what it's worth, the carburetor problems from deteriorating fuel we see on this engine brand are seen on other branded machines that use the same engine. Not to mention all of the "big 3" small engine brands (Kawasaki, Kohler, and Briggs) all deal with these issues as well.

The situation is just extremely variable with the fuel. In winter time, many places use gas that has more ethanol in it than what's used in the summer. Some places have more a humid winter time than in summer. Temperatures are different. All these things come into play on this. Mainly the ethanol causes the most problems. Ethanol causes an awful lot of problems with small engines. Small engine manufacturers are working with fuel makers and congress to try and figure other options in regards to new fuel standards because it's causing so many problems.

Because of all this, I do recommend using a fuel conditioner (like Sta-Bil) to help maintain the gas if it's not going to be used pretty soon.

Thanks Wade, If I knew it was going to fail to start if it sat for 6 weeks I never would have bought it! My lawn mowers sits for 3 months, my motorcycle sits for 3 months, I have aboat that sits for 6 months and I had a car sit for a year but don't let a brand new Craftsman snowblower sit for 6 weeks! Seriously gas does not break down in 6 weeks. There must be some corrosion going on that is clogging it up. Bad metal from China would be my guess!

I will return it to be fixed because it is still under warranty.
When I get it back I will let it sit 3 months in the sumer and try to start it.
If it fails I will return again and then put it out front for sale.

They should rename Craftsman to CRAPSMAN!
I didn't see other brands with the same motor having problems just Craftsman.

The primer will not get harder to push as you prime it. If there was fuel left in the machine while it was put away then it's almost a certainty that the carburetor now has some blockage due to the deteriorated fuel deposits. The float sticking is a possibility, but unlikely. Typically we see these carburetors get stopped up from sitting with fuel in them pretty quick (6 weeks or more).

I have attached a document detailing how to get the heat box off so the carburetor can be accessed. Try taking the bowl off and using carb/choke cleaner (spray can) to clean the bowl and spray some up into the needle valve area and any other holes you see there, then see if that works. If it does not, you'll need to take the carburetor all the way and really go through it cleaning it. Usually that only needs to be done when they've sat for many months with fuel in them though.

Thank you for using Manage My Life!
