That maybe just maybe 32 1F2 not IF2.
Should be marked on top cover somewhere.
Looking at a Haynes manual for R9 and R11 from 82-84 it was used on 1108cc engine variant and looks very much like your pics.
2 versions. 1 manual choke-code V10501.
1 with pneumatically controlled choke- CODE V10501B
Book has some good info on stripping and setting up if you can get a copy. Maybe worth fixing rather than replacing.
Check out

Haynes book 0822 covers models 82-89 which seems to be the last year they made them in France. Maybe made in Turkey for a while after that.
