Thanks Nate, The curious part of me will ultimately win out and I will take it apart and check it. But I am giving the refurb engine some serious thought. The weather is getting close to running out on me here in the next couple months and then I am going to put it up on my red Sears jack and start going through several things that I didn't do last year. I gotta get my car fixed first so that I can start using it for work. Funny how there are always projects to work on.... Do you have any thoughts on the refurbed engines?
