gizmo666 Posted November 28, 2012 Share Posted November 28, 2012 if it runs better on reserve than on main then you may have fuel tap problems ie dirt or something blocking the tap solution strip the fuel tap and clean this will probably sort the missing problem also check your float levels in the carbs the carbs could be needing cleaned/balanced hope this helps Link to comment Share on other sites More sharing options...
