Default Need help with an O.S. .61 RF

Hey Guys,

I was lucky to snag a Summit III with an O.S. .61 RF motor. The motor looks new but the bearings were rusted and pitted, so I replaced them with some Boca Bearings. It is not a pumped motor, but it does have a pressure nipple on the backplate of the motor. It has a nice tuned pipe but they have no pressure tap on the header. So the question is, do I just use the pressure tap on the back of the motor? The tank is mounted on the CG and has some pretty long fuel and vent lines. Will the crankcase pressure be sufficient to pressurize the tank. I always ran the Hanno pump motors back in the day.


Thanks,

Maddogg
