I was wondering if any of you know the stock size of the rattler carb. Thanks.

Pretty sure it's a 19mm, yep, the same as a 50cc machine

Nope, not quite a 19...the carb bore is rectangular/oval (maybe 17.5 mm high x 12mm wide, give or take); the carb bore is much smaller in the center than it is at the manifold side, or the inlet side. The bore flares out to almost a 19mm round circle at the manifold spacer. The stock carb would work much better on a Rat if it had a true 19mm bore.

Im using a rattler carb on my buddy as of right now and its been trating me better than the stock buddy carb. Plug and play good upgrade when installing a head. Im gonna do a rattler motor soon. So this was just to get my scoot up and running smooth.
