When I run my 6hp Johnson, Model 6R78B the water in the barrel ends up with good quantity nof oil residue. I have had to replace the fuel pump. Low speed needle valve, needle packing washers and neoprene washer, but still see the oil residue. I would expect to see some residue, for a 2 cycle, but how much is too much and what can I do to correct?

I'm no expert, but if it seems excessively messy (even for a 2 stroke) I would suspect your fuel mix or slow speed needle setting. What's your fuel mix?

Imo, if run in a barrel....you're going to have quite a bit of residue. It's got nowhere to go, so a little, looks like a lot.

How do your sparkplugs look?

FWIW, my 25hp, ran in a barrel....leaves a nice oil slick behind, and seems to smoke like a broke stove....but out on the water, you barely notice the smoke.

Re: Running to rich

The barrel is not the proper indicator. Set your carb jets properly and don't worry about what is in the barrel. Keep in mind that 2 strokes motors do not burn all the fuel. A reasonable amount of it goes right out the exhaust without burning. Since oil/gas is less dense then water it will float on the top of your barrel and look messy. All normal.
