ok guys i got another one for ya. (sorry not related to welding) the guy converting my engine shot me an e-mail and said the engine is all re-assembled and running. BUT there is what he called a severe vibration while running. it ran smooth in the chainsaw and we are thinking it has something to do with the removal of the flywheel. it has EI on it now so there is a nice looking hub where that used to be. anybody know what to do or ran into this problem? i need to ratify this problem so i can get the engine one the plane and order my muffler from Mr.Lambert.
