Hi Norm, Naz was after the GXV160 carby, depth perception is harder to see in a photo (looking at some of the above ones), it's easy to order the right one from the images online.
Hi Naz, with the carb gaskets you have a few choices, I usually just cut my own from gasket paper but the side of a breakfast cereal box would also work or buy some online.
The only problem sometimes with buying a new carby is to make sure the throttle butterfly and choke butterfly open in the correct direction for your motor.
