Here's one from OS:

"Fits the following O.S. Max carburetors; 2D, 4D, 4E, 6B, 7D, 7L, 86, FS-70S, FS-91S, FS-120S-E and FS-120S-SP
Note: This also works with the OS MAX 140RX engine (70A carb)."
The 86 is the carb on the pumped SF and RF. It would probably fit the Hanno, too. But, at $31 it's a little steep.
