Although the .61FSR is not the same as the .60FSR, there
was an option for a Perry Pump and Carb on both the .60 and .61. See photos. First two are pictures I found online from another one that sold awhile back, last 2 pics are from my engine. (It's been in a bag for over 25 years all disassembled). This isn't a homebrew installation best I can tell. There are lots of pictures of NIB examples of these engines with the Perry "kit".
The engine did crash and probably why the brass inserts in the carb are all wonky.
