Nobody mentioned it - but be sure you have your engine well mounted in a test stand, or in an aircraft that is tied down. You should have start up and break-in instructions with your engine - if not, contact the manufacturer or email me with the type of engine you have and I'll see what I can do.

Don't mind the humor of some of these clowns, they are really nice people. Some have been sipping too much Methanol tho!
