The French sites I looked at say the CS330 is the same carb as the CS360 and CS370 (190cc.fr who supply genuine parts). On the other hand the carb for the 333 is the same as the 335, 338, 435, 436 etc. So on the basis of that I would say the 335 carburettor you have found isn't suitable. Try searching for the 360 Oniongrower.
