These engines are pretty bullet proof. I just ran one that my brother in law sold me with the runabout that I purchased from him. It was kind of thrown in the deal. My model is a '74 and probably had not run in 20 years, but fortunately was stored inside. After doing the similar things as you, it started in 2 pulls and runs sweet. Nice engine.<br /><br />Jeff
