Mikey B Posted May 28, 2018 Report Share Posted May 28, 2018 Hi, Try the fuel tank breather screw it may be screwed closed creating a vacuum in the fuel system. Failing that a carb clean may solve the issue sometimes the pilot jets get block if it's been standing idle. Mikey B Quote Link to comment Share on other sites More sharing options...
