I have found on the Big E that the #1 or #2 setting is just about useless! I have sat for hours trying every adjustment possible and just can't seem to get it to burn decent! as soon as I go to the #3 setting it burns great and wishing I could use the #4 or #5 setting more often but Breckwell doesn't want you to use the #4 or #5 setting for more than an hour. Thoughts or suggestions?
