Pulley sizes for new belt drive build

Hello everyone, looking for help with pulley sizes… I’m using a Honda GX630 and a General Pump TSF2019… Bought the pump from Kleen Rite and asked them, but unfortunately the man I spoke with didn’t seem to bright… I tried to get a phone # for General Pump, but could only email them a question… Still waiting on them… Thanks ahead of time… Greg

2bk32 (3.35in) is what used for 18hp to ts2021. Ill look for the pump pulley size. Thats for 1in shaft.
Ok, 2bk90 for pump.

Post up what general pump tells you when you get a chance.
