My mistake on the list number , it is 6210-1, but here is a photo of the carb. And it differs from the 6210 carbs I have found. No transfer tube,center hung floats, dual feed. And it is a spread bore. For some reason I was thinking it is a 800. I have had this thing for years and need to put it on a 454 but if it is a 650 I hate to spend any money working on it.
