It has everything you need, assuming you have the transfer tube I mentioned (you need to take the metering block off to know, I simply don't recall, nor is it in my notes).
Only thing it does not contain are floats and VS diaphragm as I buy these elsewhere, tho in your case I think I'd look at the existing parts before replacement.... in my case the carbs are for sale, so it's just a good practice to change them.
