Ted what makes you think you are lean?
What did the carb come with from builder/manuf.?
This weekend could be deceiving, the temp is up... But the Barom. is VERY high 30.32"

A weather station is needed to keep track of DA/ ETs.

The only way you can get a .1 sec ET on tuning is if you were WAAAAAAAY off to start with.
More info and good luck, Don
