Your setback thermostat has nothing to do with the burner firing, other than it calling for heat. The ignition system and gas valve are entirely seperate from the stat.
If you do not have a fan-assisted burner (ie.. chimney system) Then the problem may lie in the gas valve not opening quickly enough to light all the runners and burners. There could also be a problem with the runners between the burner that lights, and the ones that dont. Your original tech should have completely disassembled the burners and manifold, shame on him if he didnt. He should have swapped positions with the burners to try and chase the problem.
The other possibility is you have either a gas main regulator problem, or water in the gas service line. I have seen this cause intermittent problems. Check for a 4-6" round device attached to the left side of your gas meter, and make sure the hole (usually facing down) is completely unobstructed. This is the regulator vent hole.
good luck
