This engine was put in an old John Deere lawn tractor.  I cant find the pulse line for the fuel pump.  I have been using the vent off the valve cover that should be connected to the air cleaner.  Its the only place I can find on this motor.  Anybody know where the actual pulse line is?  Not sure if its a good idea to use this port for oil blow by or even a solid consistant  pulse for the pump
