Hello Ted, did you do a video demonstrating how to do a vacuum test? Thanks for the great videos!

Not yet, I will make one in the near future on several different engines. Good idea!

Hello ted. Quick question. I have the engine on the boat and need to advance the engine so I can see if everything is moving correctly. How can I do that? The motor mount is right in front of engine.
