Snowblower won't start, like no gas going thru

I have a yard machine snowblower, it was just overhauled because I left gas in it for 2 years which turned to varnish, so all the lines and the carb were clearned. I just tried it today it worked for 10-15 minutes then shut down, like it ran out of gas, but there was plenty of gas. I tried to start it again, and it started and ran for 10 seconds. Now it just keeps turning over with out starting. What am I doing wrong This has an electric starter. t has a Tecumseh engine

If the engine is infact seized, then it will have to be re-built or replaced. It was probably run with very low or no oil at all. You may be able to get a short block for your engine. All you would need to do is reuse your cylinder head, flywheel, carburetor, ignition modual, recoil houseing, fuel tank, governor linkages and controlls. The engine block and all internal parts would be replaced. It is far cheaper to just replace the engine rather than re-build it unless you are able to do it yourself and save the labour cost.

Sounds like the timing may be off or maybethe exhaust valve maybe hanging open.

Hope this Helps.

Not the solid state ignition. If this were the problem the engine wouldn't start at all. There is some adjustment needed to the carb but without more info, I'm not sure what.

I started this snowblower in the summer and it worked fine...both winters I've tried to use it it won't start. The first year I had it it worked very well.


So you are saying it wont run in the cold. Will it run if you left it in the house until you wanted to use it?
Are you going thru the procedure of Choking the engine ? Is there a Primer Bulb that you have to push on this machine?
I'm just saying that engines don't like the cold to begin with, just make sure you are going thru the 'Cold Start' procedure properly.

When in gear right wheel drives left wheel is locked and will not move same when not engaged


Many snowblowers use pins (or bolts - see image below) that pass thru the shoulder of the rim of the tires thru a hole drilled thru the drive shaft. Removing both of the pins allows the tires to spin freely on the drive shaft and makes it much easier to push, pull and turn the snowblower. If they are not installed again, the machine will not "drive" and make clearing snow difficult to do. Installing only one will make the machine want to go in circles. Make sure you have these pins installed thru BOTH rim shoulders and drive shafts - locked in place. Other machines lock the tires in other ways - since it sounds like one side is working correctly - you should compare the two tires / rims and make them both look like the one that works properly. Good luck!

Craftsman Snowblower Won't Start


If you did not put gas stabilizer in your fuel tank when you stored your machine the gas will turn into varnish. Try draining the gas and put new gas and try to start it. Good luck

Not getting any gas


Most people leave gas in the tank year round. This is a problem for engines that are only used a few months out of the year. Old gas will cause the carb to gum up and not allow gas to pass thru into the combustion chamber.

You will need to pull the carburetor part and clean it.

check out this YouTube video. It shows how to clean a single stage snowblower carb

How to start the snowblower yard machine when you've tried everything to start it up correctly and it doesn't start?


How did you store it? The gas should be drained out of the carburator and tank prior to storing. If you don't do that it starts varnishing the jets closed in the carburator. So to start it, try draining all the old gas out. Take the spark plug out and put the wire back on and lay it on top of the block. Crank the engine over turn switch on if it has one, does it have spark? If it does good. If not try a new plug, if it still does not have spark you will have to pull the flywheel to see what is wrong with the points or pickup. Once you have spark established, put new fuel in tank. Spray a little WD40 into spark plug hole. Put spark plug back in and go through normal starting procedures. Good luck.

Based on you question, this could be anything (like going to your Dr. and telling him "I'm sick"). That being said, if it just sat with gas in it, then it's likely a fuel problem (ie; plugged carburetor). These machines do not like the new Ethanol Gas and they cannot be left to sit or they'll gum up on you. An engine needs three things in order to start and run. 1. Spark 2. Fuel 3. Compression. First check your spark; if there is no spark, it'll never start. If there is spark, then I recommend a good carb cleaning. Better left to a professional if you're not familiar with this procedure. I hope this gets you started in the right direction. Best of luck to you. (You can find "how-to" videos on all these procedures by searching on YouTube)
