I posted last week about a 1995 merc 150xri efi not starting when hot. just purchased boat and learning this system. found out ign system all correct. very rich condition floods after ran at lake. got it running smokes bad got home checked fuel pressure 37psi and holds for 5 min ran inject clean bg pres clean. checked all sensors tps ok ect ok map vac test ok bar ok don't have merc scan equip. I am master auto tech 30 years exp know efi well. I have raw fuel pulsing from bleed hoses at idle it has manual valve at vapor separator that functions ok is this adding pree mix back into fuel system causing over rich oil fuel mix. also read about float in vapor separator could this cause my prob only have clymers manual not to distinctive on operation of this system or maybe check valves causing prob but did not clean up smoking after disconnecting bleed hose but may have over oiled fuel in system. also inj clean system I use on tank fuel line to engine took in 1 qt cleaner in 1.5 min that's a lot of fuel. any help please
