There is a plastic reed retainer instead of a g-clip. That is fine. The reed appears to be 90 degrees from ideal, but they float so probably don't stay in the same place. (no big deal)

There might be no gasket as the plastic retainer will act as a gasket. (Not recommended, but allows for a more stuffed case. It works if the case is lapped and the tank is smooth.)

There might be a gasket between the case and plastic retainer (I believe this is considered "normal")

There might be a gasket on either side of the plastic retainer (I believe this is an extra gasket, but also considered "normal")

Nothing unusual just a later version. I think around 88-90 is when they switched to that style of reed retainer.

Personally I like the look of the older clip style, but like the functionality of the newer one. The "G" clip has a tendency to impede free floating of the reed whereas the newer style allows 360 degree rotation.

As Phil mentioned gasket is not needed if case is flat, but from new it could come with or without.

I think they run best with that type of reed retainer. Make sure the o ring on your venturi is in good shape. It might have an air leak. Try some gaskets between the reed retainer and the tank and crankcase. And I would cut the tip of the pickup tube at an angle too.
