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

I suspect that the main jet in the carby is blocked
It could be that the needle in the carby is stuck closed
There could be water in the carby
I would pull the carby and have it overhauled / cleaned out

Yard machine snow blower wont move wheels locked up model 31as6fee729


check for rusted shafts and or bearings as you use this machine a few times a year in the worst possible conditions and the rest of the time it sits idle in the shed.

Our HMSK 80-110 electric start snowblower starts up right away, but the idling is very rough. It runs very smoothly when it is engaged in snow throwing.


The Tecumseh snow motors are notorious for idling rough. Especially the last few years of production. Most service techs just say "live with it" But there are a couple of things you can do to help.
It is not a carb adjustment issue. It's usually a fuel, clean carb issue.
First, use a premium grade fuel without ethanol and a fuel stabilizer. This will give you the best fuel mix.
Second, Remove the carburetor shield and clean the inside and outside of the carb with carb cleaner. Even though you can't see the carb usually, they do get varnish build up and cleaning it will help some.
Third, Put the recommended amount of fuel system cleaner in the gas. I use Sea Foam brand. Over a tank full or two you will notice a difference in how the engine idles.
Fourth, Use a high quality spark plug and use a new one every year. Make sure the gap is correct.
Good Luck! Feel free to as any other questions you may have. Don't forget to rate this answer!

MTD YARD MACHINE SNOW BLOWER DOES NTO SHIFT INTO


Many times moisture attacks the hexagon shaft that the friction disc assembly slides on. It slides from side to side on the shaft to create Reverse 1 & 2, and the other end creates 1-6 forward. With a wire brush and sandpaper, clean the rust from the hexagon shaft, at the same time lubricate the friction disc bearing with penetrating oil and with a soft hammer, tap gently until the assembly starts to slide on the hexagon shaft. After all the rust is removed and disc assembly is sliding, apply a light film of graphite grease on the shaft. You may want to re-lubricate on a yearly basis.

Snowblower wow's


tecumseh snow engines are natorious for not starting,first thing you need to do is take the old gas from the tank.gas only stays good for about 30 days.YEP .....that's all.there should be two screws that holds the cover over the carb.take the bowl off and there should be water and dirt in the bowl.clean that out,be careful not to drop the needle off the float.if you do it take a little patence to put it back on.now the nut you took off the bowl has three holes in the side of it.clean all the holes,one is really small and it's up twards the theads..replace the bowl gasket and reassemble the carb.now you should have fuel to the cylinder and it should start.if not let me know

I have a yard machine snowblower that will not start


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.
