Tecumseh snowblower revving high

This weekend I picked up a couple snowblowers off Craiglist, one of which was an Ariens SS522E with a Tecumseh 139cc 2 stroke. It ran a little rough, so I did a carb clean and reassembled. It was strange, because the carb appeared to be new. Upon starting back up, it still ran rough, but after a cou..

Tecumseh HH70 No Spark - Points & Timing Issues

LEV120 Crankshaft Binding

I'm not sure why something that should be so straight forward is causing me so much trouble. I appreciate the help from SRTsFZ6 so far in my prior posts as I'm new at this. I'm working on a vertical shaft LEV120-362003A 6.5HP from a 2003 Toro mower. It hit a hard object that resulted in a cracked su..

Flange Cover/Crank Shaft Question

After replacing the flange cover on a LEV120 shouldn't I be able to hand turn the crank shaft? This is my first time doing this, so I have no idea what's expected. Before reassembly I applied a light coat of engine oil to the cylinder wall and other internal parts including the oil seal on the flang..

Any interchangeability among HM80 engines?

Hi, All - I'm trying to help my Amish neighbor get a replacement engine for his log splitter. The model number of his engine is HM80 155653S. I've found engines on both eBay and Craigslist that *look* comparable (e.g., a new HM80 155432M, with a 1" diameter crankshaft that's 2 and 3/4 inches long),..
