Here's some thinking. Would think Jetting it would be a pain?
this engine was given to 44ch for a 250 in 1975 it is quite the carbus 32 mm, in fact the aim is to have equivalent gas passage has a 45 mm while retaining a high torque, gas flow rate the 2nd carburetor returning offbeat way action settings on the PUCH 250 TFS (1951) with its two carbus 27 (equivalent 38) is relatively easy, cross aperture is very progressive, but presented engine I do not know, but I would have liked to see this.
