dont know the year serial#3535530. owner before me had carb off. it is a side bowl setup. there is a screw on the very top of the cover that is part of the bowl assembley. is this screw an adjustment for anything? there are two other screws to each side of this cover below the one in question. if so what does it adjust? ive noticed if it is to loose fuel seeps from the bottem of it if it is to tight does seam to run right. under this cover is the float assembley. thanks
