Listerman77 7 #1 Posted June 12, 2016 (edited) I am restoring a Ransome's triple with a mag twin cylinder petrol engine. Engine runs as if starved of fuel. The fuel mixture screw has no effect on the engine speed or exhaust colour. I see others have had this problem. Any ideas? Does the gurtner carb block up somehow?
