Hi Mitch
That asymmetric combustion caused by the air delivery tube positioning at the Primary Zone end of the combustor is easily fixed by placing it in the "best" position at the outlet end of the combustor ..............why guys persist in fitting it at the primary end I don't know , why place it at the point where only 30% of the air is needed and cause a lot of problems , place it at the other end where most of the air is required , the Primary zone won't be starved of air if the hole area of the flametube is correct .
Blanking off holes on one side of the flametube is a case of "two wrongs trying to make a right" , with blanked off holes combustion is going to be affected , with the air entering at the outflow end of the combustor the air has time to even itself out by the time it flows up to the important Primary end where it can enter the flametube in an even flow around the entire flametube .
Cheers
John
