There are a number of possibilities, the two that come to mind right off
are: Jet alignment and erosion of the burner tube. Either will cause bad
turbulence and hurt performance.

Another thought if you want to call it that seeing as I don't recall if you
said these were commercial burners or home made, sooooo much time has
passed. <sigh> Anyway if these are commercial burners the jet is probably
specifically designed for induction. If it's fouled it won't work well.

I know it's ridiculously critical where oil fired furnaces are concerned,
ANY damage, wear or gunk and the old boiler starts acting . . . badly. I
know we're not talking oil but a commercial device is often built to very
tight tolerances and any damage can really degrade performance.
