yeah I don't know why he took it out, he claims he couldn't get to the screw! So thier is a certain way the thing is supose to go back in? We lined everything up except for the main body and the part that spins at the bottom.
yeah, that part that spins at the bottom is one thing you really do need to put back perfectly, otherwise its like advancing or retarding your ignition timing like mad. if it's way off, you won't get a damn thing out of the engine, but if its only a little off, you can seriously start breaking things in the engine when it fires halfway thorugh the compression stroke or something and makes the engine try and turn backwards
