Thanks. I tired that today and it made it worst. Maybe I went to far. I normally check my low end 2 ways. First I let it idle for 30 seconds and then go full throttle. I look for a smooth transition. Secondly at idle I pinch the carb supply line and see how the motor quits. I want it to quit without speeding up too much (ie. too rich)

Do you have a method for checking the low end?

Yea I am keeping it high until I figure out what's going on with the midrange!
