Hi,
Sorry but I'm not too good on theory but have made a burner for a Cracker. Hopefully the following photographs will help. A small air hole was made in the burner tube in front of the jet. This hole was enlarged until the flame looked right and was controllable high/low.
Small hole.

Larger hole high setting.

Larger hole in low setting.

Test in flue tube same size as fitted to boiler



Hope this might help.

Regards Tony.

FWIW, my Cracker burner doesn't burn for beans outside the boiler, but roars away when installed, so be sure and try it installed as well.
