Default Wisconson S12D Operating RPM?

Does anyone know the operating RPM (the RPM that 12 HP is delivered) of this engine. I bought an old asphalt roller that I need to bring into service ASAP. I can get a 13HP Honda that I think I can shoehorn in but I need to get some idea of the pully dia to maintain the original speed of the machine.

Any info would help, Thanks
Buddy Harley

Wisc S12D rated at 12.5 hp @3600 rpm. From ASECC's info tables.
All I could come up with at the moment.

Thank you Mr. Ruffle! That is about what the Honda runs. I can consider that to be one possable problem solved , that leaves only about 6-8 more. The rest should be gravy!
