Ran my 86 70 hp on the stand. Intermittent stumble and starts to die. Took off airbox lid found milky looking fluid coming out of carbs and at base of airbox. Any ideas?

It's also pushing oil/ fuel mix out of small hose at bottom of airbox when cranking engine. Compression is 120 warm across 3 CYLINDERS

It's been purchased from someone that had it sitting for a long time. It has good compression and good spark so I tried to restore it as a good running motor (I also part out motors). It's a 1986 model e70elcrd. Probably just going to break it down for parts at this point. If I don't trust a motor I don't sell it as a whole unit. It's a
Freshwater motor with many good parts on it including a pressure tested lower unit with brand new omc pump and an excellent working power trim unit. I wish I lived on a body of water so I could boat test my motors but it is what it is.
