It wont rev much past idle and smokes heavily , starts 2nd kick, smokes that much has black oil leaking outexhaust at motor, have changed settings on carb but no joy but then carb seems well worn and everyone has had a go at it. Any ideas anyone!

+1. From memory it can be fixed without splitting the crankcase but it's been a few years so don't quote me on that call!
