went to decarb my engine and under the hood I noticed a film on everything. I started it on the muffs and noticed a small amount of smoke(im sure exhaust) coming from under the power head? Now what is this? Also seemed a little oily under the hood as well. The carbs every now and then will spit gas out while its idling. The motor runs spot on but this cant be good? Any suggestions
How long has it been stored and where? My 30 evinrude was doing the same thing, back flushed thru prop hub and my nemesis adobe hotel came out, I hate mud daubers, big and small, have to cap every air tool, blow out unused drill press motors and pulleys, etc., etc. etc. I hate mud daubers, Did I mention?, I loathe mud daubers.
could also be an exhaust leak getting under the cowling
The fact that the carb spits gas makes me believe the exhaust is restricted. Have you been using the cheap oil that WallyWorld sells, you know…the stuff in the blue jugs? I’ve seen exhaust ports clogged from using the cheaper oils.

I have had problems with the mud daubers I will have to check that. I thought I was using ok oil… Penzoil. I would think if it was clogged it wouldn’t run well at high rpm?
I did notice that the air cover gasket was missing. I would think that’s what caused my oily mess in the bottom of the pan. if the carb was spitting a bit then it would drain out onto the bottom of the pan?

I missed the part where you said the motor runs good. If it was clogged, the motor wouldn’t make full power.
