Question about Tecumseh Horizontal Tiller Engine 8 Hp, 1" X 2 57/64" Shaft, Modelno. Hm80 - 155656x
Have a Yard machine snowblower,runs great,gear lever moves freely (too freely),won't move?
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.

hello ,your engine is a tecumseh HMSK90-156525D, Sounds like carb. may need adjusting. Take the heat box off to expose carb. the heat box is the metal box surrounding the caeb., there should be 2 adjustment screws- 1 on the bottom of the bowl and 1 on the side of the carb just above the edge of the bowl ( depending how the carb sets off the engine - if the carb comes straight out it will be on the side facing towards the front of the snow blower or if it goes towards the handles then standing other side of the snow blower the screw will be facing you), turn both screws in til they just bottom out the turn them out 1 1/4 turns out then start the machine. While the machine is running at low idle turn the screw on the side of the carb. in (clockwise) a little at a time listening for the engine to start to rev up and then start to rev down, bog or studder then turn back slightly to bring idle back up. Once the idle is up then the screw on the very top of the carb. turn that out to lower idle to a normal idle. Repeat those adjustments till you cant get the idle to go up anymore. Now for the screw on the bottom of the bowl- move the throttle up to max and turn the screw in till you hear it rev up higher and starts to bog or sputter then turn it back slightly to bring the high rev to a smooth rev. That should take care of it. If it does not solve it then the carb may need cleaning then the adjustments done again. If you need more help on this please feel free to ask. Sometimes you have to do process of elimination and you start with the easiest first. Also the adjustments should help with the carbon build up on the plug.692509.pdf (application/pdf Object)

Had the same issue and found out that the wheels lock when the motor isn't running and the accelerator handle is engaged. I still had both handles tied down from transporting home and it rolled fine after they were untied. Hope that helps
