RE: YS 170 DZ CDI
Hey Chris
I can get it started by capping the vent , pressureizing the tank, go to full throttle. then spin over with starter. I then release pressure turn ignition on and start engine. It will run out the prime and die! When the pump is working correctly all I have to do is go to full throttlr, no ignition, spin over with starter, turn ignition on, go to high idle and engine will start and run fine.
