Get the Burner manual for the Powerflame from their website. They have good troubleshooting and set-up instructions. Check your flame sensor for dirt. Check to make sure on startup that your air dampers aren't too far closed. The pilot needs combustion air too. Check your electrodes and pilot gas pressure. While you're at it you may as well pull out your analyzer and check the CO and set up the burner at the lowest fire and the highest fire. Also, set your check your firebox pressure and draft. Usually someone screws around so much they screw up the burner settings completely. Especially, the full mods.
Did I mention to make sure the dampers aren't fully closed during trial for ignition?

Txvsrule is right, particularly the firebox pressure, I have found Powerflame burners to have much better pilot reliability when the firebox has a slight positive pressure. I remember one particular boiler that was under warranty, it would have random pilot failures until we added a baffle in the flue collector to give the firebox a slight positive pressure
