Is this a new (rebuilt) engine? Or is this an engine with miles on it?

If it is rebuilt, I would already believe that my settings on assembly were correct and expect it to run. I wouldn't even do a compression check unless I felt something was amiss, or until after my initial first start and run at least.

I'm a little confused Joe. Why would anyone be checking an engine without the cam timing correct? Wouldn't that all be buttoned up by the time one got to that point?

And, the cam would already be prelubed with the cam lube when assembled. Why would spinning the engine over with the starter hurt the cam any more than starting it the first time?
