i needed to replace the floatbowl gasket on my carb since it was totally hardened.
Since the whole gasket kit is just a little bit more expensive then a single gasket I went for it and replaced all the gaskets while I was in there.
Simple enough on a PHVA.
There are also some rings and gaskets you might not need, but better to have them the to need them.
Original Dell'orto so very good quality and fitment.
