Octotat 15 #1 Posted 3 hours ago Hey all, The little Tecumseh 7 hp in my WorkHorse 700 is getting tired. Tons of blow by and oil leaks. It's also missfiring worse and worse. I would like this forums advice on rebuilding vs replacing it with something newer. It currently has an electric start which I love and I know going to some repower options I would lose that feature. If rebuilding it is the way, any kits or other recommendations? Share this post Link to post Share on other sites
ri702bill 11,965 #2 Posted 2 hours ago Welcome! Some parts - oversize piston, rings, perhaps more are either discontunued or very difficult to find, as Tecsuseh is out of business. Yet valves & gasket sets are available. You either love or hate Tecky's.... The issue with a repower is does the replacement engine have a bushing or a ball bearing (required) at the pulley end of the crank to live with the side load. Most do not... A populat upgrade is to ditch the Tecumseh and replace it with either a Kohler 7 HP K161S or an 8 HP K181S from a Wheel Horse. Direct proper drop-in replacement with great part availability. 1 Share this post Link to post Share on other sites

That old style PTO doesn't put end pressure on the crank so no ball bearings are needed. 1 1 Share this post Link to post Share on other sites
