Hi, could use some help. I have a 1988 glastron z-16 with a 1989 Force 85 HP (858F9B) outboard motor. My problem is carb #2 spitting out the overflow at low and medium speed (engine bogs when this happens, as expected). - compression test 115psi all three cylinders - spark and firing all three plugs - rebuilt all three carbs, boat ran great for a week. - boat ran out of gas and the trouble started (carbs spitting) - emptied and cleaned gas tank. fresh gas. ran sea foam through the system. Took apart all three carbs and cleaned ( fully took apart, carb cleaner into every hole, soaked carb body in gas, compressed air to dry, reassembled, ran great for a day, # 2 carb spitting again. - Since it ran great for the day (6 hours) I think reed valves and fuel pump are good. - I keep coming back to needle and seat and maybe float. Will buy a new needle and seat and put float in water and watch for bubbles. Cant buy a new float at boats.net or marinengine.com as it is unavailable. - what else am i missing? I started knowing nothing and now seem to be just about dangerous but still not successful! any help would be appreciated.
