Hi!
I'm the happy owner of a Volvo BM mini. I don't know which model number but I believe it originates from a Roper RT 16 (imported by Volvo...)?
A metal plate says: model no: T63231RO and serial no:1312
A new battery and cleaning the carb did the trick and now it is running. For idle and main jet screw and backed out both of them 1½ turn. Does that sound reasonable?
Best regards, Asger
