Another thought. The ultimate mixture is set not by the main jet, but by the power adjust needle. Main jet & power adjust needle are in series , so the smaller opening sets the mixture. If you can back the power adj needle out far enough (3 + revolutions)to make it run rich (black smoke)then you can be sure that main jet is plenty large!
