Question about Tecumseh Horizontal Tiller Engine 8 Hp, 1" X 2 57/64" Shaft, Modelno. Hm80 - 155656x
I have a 824 Toro snowblower. I was out tuning the carb after a float repair and replacement. When running the auger I could hear what I thought was the impellar stiking the auger with every revolution. Sure enough it was. How do I move it the impeller back or is it a problem with the auger. There are two screws that were loose around the pipe that goes into the auger. Now the auger wont move at all, it is not caught on the impellar?
Any ideas? 30cm coming tomorrow!!

One of two things will cause this. Either your piston rings have fried and your piston is stuck. The bearing on the flywheel is bad. Or actually one of thing, the crank shaft has broken. You willl need to take the motor apart all the way and see what is going on. If you take the flywheel off try to turn it by hand and see if you can turn it that wy. You also can try easier to check for first symptom is to make sure you are not in vapor lock. Remove the spark plug, turn unit upside down and see if you can get the motor to turn, if you can then replace the spark plug and it will start up. You can getvapor lock by running it low on fuel or the wrong fuel or running it to rich

whithout the engine running the gov should be trying to full throtle. when started this should tell the carb to supply or restrict fuel/air to compensate for load or the lack of. but to answer your question....yes the gov should be wide open, unrunning.

either replace it or short block it, either way you will be re-newing the heart of your machine..... short blocks are typically less expensive

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!
