RE: Welcome to Club SAITO !
Jett:
I have always tried to minimize vibration. Since the vibration is what makes the VP-20 “Shaker” pump work I have never used one. All of my several pump installations use the VP-30 pressure actuated pump. The VP-20 does work though, or people wouldn’t use it, and Conley would not have a market for it.
The sensitivity of the LS makes me think your pressure is high – turn the pump regulator screw out ½ turn and see what happens. If the pressure is high this could also be contributing to the mess on the bottom of the plane – it’s running rich at low and part throttle. How’s your endurance? Is it guzzling its fuel? Another rich indication.
I see you’re not running an air filter. This could also add to the mess.
Regards the vent. I have long felt that positive crank case ventilation was like running a hose from your back end into your left nostril. The aroma wont offend others but you’ll have a smelly time. The engine is running a “Total Loss” oik system, it’s intended to blow to the air. Normally I’d say if it’s too much run the vent hose to the rear of the plane, but with the pump that would again raise the pressure with the added restriction. Still, you can try it and readjust the system.
