[QUOTE="biglou, post: 208796"] [b]Re: Top Dead Center.[/b] Top Dead Center, or TDC for short, is when the piston in at the very highest point it can travel to inside the cylinder. You want it to be just past TDC before you kick it so you don't break your leg or the kick starter trying to push the piston past TDC on the compression stroke. This is why you kick it until it essentially stops due to the compression, pull the decompression lever and let it go just a bit further (past TDC) so that the piston is on the down-stroke before kicking it.
