Even though the Tecumseh I just installed is old, its runs strong. No blow by, no oil leaks,nothing. Hopefully it will stay that way a long time. It had just come off another splitter that has split hundreds of cords of wood, but the owner was tired of the starter messing up. He found himself replacing the starter yearly, so he said the hell with this and changed out his motor. The new starter I just put on appears to be the right one while the others bolted up slightly different causing alignment issues. Depending on my reflexes with the stop watch, I'm getting 9.3 and 9.5 second cycle times. Thats faster than the TSC and Lowes' brands LOL.
