Vintage Trim Rite Edger Briggs & Stratton Engine Turning over, not running

  
Vintage Trim Rite Edger with Briggs & Stratton Engine. Turns over but doesn't start. Obvious signs of use, blade turns fine when pull cord is pulled and sounds like it wants to start but has been sitting for many years in a garage! If nothing else, would make a lovely collectors piece for someone who enjoys vintage garden machinery. Collection from Sheringham NR26 or NR24 Melton Constable.
