Hello,

Have NIB BVM fan unit from the market. (no box or part#)
Tried the OS 91, OS 77, Rossi 91..........
nothing fits the mount
Does the BVM 91 have a smaller crankcase size?
Will a K&B 82 Fit also ?

Thanks
Cassat

You need the BVM .91 for it. You could also use the BVM .81, .82, .96, or even an old .72.

The K&B .82 has different mounting lugs I believe. There was almost nothing that would interchange between a KBV .82 and a K&B .82. They were totally different engines.

John,
Thanks for the valuable information. That was what I needed to know.
Much appreciated.
I will look for a Ramtec fan for the Rossi 91
