If there is a pull handle on the handle bars, then check beside the engine, for a tin housing that may cover a drive belt. If not that type, then check for a tin cover, in front of the engine and between the engine and the blower tube/housing. If that type-then check for a disconnected cable under that housing. If the other type, on the side, check there for a broken or disconnected cable. I would suspect trouble under the front housing. It is usually held in place by several screws/bolts.
See what you can find, and report back. RJ

TY RJ, report back soon
