Just got my 5200 carb from Stovebolt, and was rather supprised to see that it had such a wierd oval shape to the top. Besides the oval shape, the carb attaches to the air cleaner with 4 bolts around the edge rather than a single center post. What have those of you who have switched to a 5200 done for an air cleaner mount? I wonder if I'll have to build a custom bottom plate to get an air cleaner to mount properly?
