Professorpi; I have been looking at some very low priced engines on Ebay and elsewhere but I don't trust them because I don't have trust in Chinese made knockoffs and their uses are for anything from a go cart to utility. I have learned for the web that I want torque and hp in the low rpm range, unlike a go cart engine that would want speed. I am satisfied using the mower deck for light brush cutting, knotweed and high grass cutting.
Borat; I found a site http://www.smallenginesuppliers.com/shop/html/tecumseh_snow_engines_feature-specs.htm stating the tec has a cast iron bore.
mm14; I almost made that mistake but I am reading alot of webpostings and learned that ahead of time. Thanks
Nibbler; I wondered if the shroud was removable. I am going to make some calls and get more info
I am find great pricing to MTD shaft engines but I can't find a pulley to go on it. I also wonder if I need to change the pulley size ratio if I go to a larger engine than the 6hp that died.
Thanks
