A new club member showed up to the field today with an old Tower Trainer (10 years) and an engine that came with the plane - a TH .46. I believe the carb is an air bleed and has a black screw with a spring around it for the mixture control. No one really knows how to tune his engine.

So what is different about an air bleed? Is the whole process the same except for the direction you turn the screw? Do you still turn it in 1/16 increments?

Thanks for your help.
