I have been asked for more truck castings including the gears, so I will be making a further run, please let me know if you are interested so I can make up a decent quantity for the caster.

I used No 6 jets in the kits I supplied, does the mixing tube go right acros the burner base? it needs to to mix the gas and air and deflect it round the ceramic block.

In our burners the mixzing tube goes right across the tray to within 1/8" of the other face, this "swirls" the gas around and helps to distribute it evenly under the ceramic, the boiler base is then about 1/4" above the burner so that the flame plays on the base as well as going up the flue.
Hope this helps
