bmwford94 0 #1 Posted June 15, 2011 i recently purchased a Tecumseh HM_80 with pull start or the option of key start. The starter is bad, but the engine came with a new one. How can i wire this starter to my key on a 1973 wheelhorse 8hp4sp? i have the original wiring that plugs up to the key switch. Share this post Link to post Share on other sites
