When you pull the recoil starter handle the rope does not reach the start of the compression cycle This is a brand new tiller that has never been used so what is the matter?

Not sure what you mean by "the rope does not reach the start of the compression cycle". Maybe the pull-cord is too short and does not spin the flywheel fast enough or enough times to get the engine started. If the tiller is brand new, it's probably under warranty - take it to where you bought it for repairs. Trying to repair it yourself may void the warranty - better to let a professional work on it.
