Large burner wasn't lighting very quickly

Removed grill grates, gas distributors, etc. (just lift off). Used star screwdriver to remove screws (3 per burner for SML, 2 for power burner). Lift off stainless cover, which also lifts off the white sparkers I was replacing. Pull them off the wires (didn't need pliers, others said they did). Replace (make sure it is all the way on) and reverse your steps. White sparkers electrodes seemed loose when I put them back on, but tightened up when I fully secured the top back on. Make sure the wires aren't pinched underneath when you put the top back on. Recommended: If you've got one that isn't working, go ahead and replace all 3 (power burner is different) because the part is so cheap you may as well just do it now.
