The Fergie version needs modification, the mounting flange holes are in the wrong place and you will need to replace the choke tube and jets with the correct size for a seven. It is much better if you can find one intended for a seven, these have 1372 stamped into the boss on top of the float chamber, I have just fitted one to a Chummy and it works extremely well. I would suggest it would be as expensive (possibly more so) to adapt a Fergie version as it would to refurbish a 22FZ.
