Ok, VRO experts. My 85 140 fouls plugs bad.Have done oil-in-plastic-tube test at idle. pumps about every 7- 10sec hence excess oiling. BUT nip off line to carbs and pulsing stops (as it should) Dont say carbs are flooding, they aint. Whats wrong with the pump? Have disconnected and ready mixed now. runs ok again. I am an "A" grade auto tech with experience with outboards. Can't figure why the pump cycles so fast when you can stall it at outlet. any ideas, oh VRO gurus?
