I have the Zenoah 260 water cooled with wet tuned exhaust from Warehouse Hobbies. I was having an issue on the low end where it was cutting out a bit so I richened the Low end. I think I have gone to far now. My exhaust has all the dark black stuff coming out around it. Almost like oil.

My directions say to set back to default:

High 1 ½ turns out
Low 1 ¼ turns out

Does this mean crank the screw all the way clockwise until it stops and then back it out 1 ½ turns?

Does the black oil mean I am running to rich?

Yes, and Yes.
When adjusting the carb, take it in 1/16 or 1/8 turns, and let the motor stabilize before turning it again. A quick snap rev, then letting it idle for a few seconds in between adjustments will help you determine if it's close or not too. When you get close, then graduate to 1/32 or less till you zero in on it. :cool:
