I think it was in the movie Hondo, John Wayne said something like " A long time ago I made me a rule, I let people do what they want to do."
I think I'm gonna let my motor do what it wants to do. I just have to do the work to find out what that is...
So I know there are differing opinions on this subject, and honestly I think everyone wants to help fellow members. But, sometimes I think old John Wayne was right.
There's not too much involved in moving a vac hose from one place to another, and testing.
