The other day I took the fire pots out of my 4 Star to dump the ash. When I restarted the grill my left pot wouldn't light. Turns out I didn't have the igniter rod aligned with the hole in the fire pot and I pushed it backwards when the pot was seated. Had to climb halfway into the grill to finally see it and pull it back out. I guess I should get a shop vac. Just a friendly tip.
