It does have cv carburetors. I believe they are bs34's if I remember correctly. I had questioned whether the diaphragms were good a while ago but realized if they were bad, I'd have no top end and that's where it performs best. Like I said though it isn't running perfectly still though so ive got some playing around to do but overall is running so much better. Good thing too because I was getting pretty tired of tearing those carbs out even though in the grand scheme of things, they are pretty easy to get to.
