Hi, not a long ago I bought Blaster, rode it all day and next day I dismantled it for small works. I replaced air filter, removed carb and cleaned its outside, removed float bowl to check what jet was there, then assembled it ant put into engine, unscrewed mixture screw 2.5 times, by the way, intake manifold is crannied, but I cant see the light watching through clefts in manifold. Mounted silencer on, becouse when I bought him, silencer wasnt connected to fatty pipe. Started engine - it ran unevenly, revving itself, but after some time it wents do work idle clearly, until I touch throttle again. Next day I went to ride it again and after some time happened that what You see in photos - mixture got very lean. What I should check, to get back the right mixture?
