Did a complete rebuild on a Merc 200 v-6 carb mid 90's offshore outboard.One hole resleeved professionally,new pistons,etc.Motor is spitting fuel out of the bleed hoses and oil tank pressuring fitting on block(injection removed)Carbs were fitted with new bowl float valves only,nothing else removed or replace from carbs.I bypassed the choke solenoid valve,same thing.( it wasn,t working anyway)Tried another fuel pump from sister motor,same thing.Motor seems to be running good and smooth on heavy oil,uses 2 gallon in 15 minutes.No fuel spilling from carb throats.This is first complete rebuild for me,Triple checked piston direction,I don't think this is blowby fuel eithertill rings seat.Checked bleed hose routing.Where is fuel coming from? May take carbs off sister motorand try,also do compression check all around.What could be happening,this can't be normal?Plumbed carbs same as sister motor. thanks
