Ok Im starting my engine for the very first time and I know Im supposed to run it rich and run thru a few tanks to break it in. I have a question about the tuning needle tho. Im under the impression that clockwise is lean and counter-clockwise makes it rich? Also how many turns does it take to go from lean to rich? I dont see a difference in asnything and there;'s no visible indication to let you know when you're actually running rich or lean. I also I cant find the info anywhere. Thanks in advance.
