On second thought maybe I will try to use the existing vacuum motor and power it off a pump. $100 is not a horrible rebuild price but does anyone know if a rebuild kit is available? It took about 10 mins and I already got it cleaned up and disassembled. After rebuilding carbs this thing would be a walk in the park. I see a few gasket kits out there but it would be really nice to get a new flapper valve.
