A few weeks back I gave my Weber spirit grill a quick cleaning. While scraping out the inside, I bumped the burner rear crossover tube and it literally crumbled. While cleaning off the flavorizer bars one of those developed two holes. These were cheap aftermarket stainless from Amazon. I'm impressed they lasted 6 years compared to the crap Weber parts that rotted out in 2 years. Anyways I ordered a new burner assembly, new stainless flavorizer bars and a new igniter assembly from Amazon.
The new burner assembly was 1/8" too short which caused it to fall out of place. I ordered a different burner assembly half expecting it to also not fit with the plan to just use the crossover tube. The new burner assembly was identical to the previously not fitting one and also did not fit. The new crossover tube also did not fit in the old burners. It was 0.394" (10mm) compared to 0.375". A trip to Harbor Freight was made to buy a drill index with a 13/32" (0.406") drill bit. The old burners were drilled out and the crossover tube fit.
Stainless flavorizer bars added.
I also cleaned out the flame slots and air intakes on the burners. Hopefully they burn more evenly. New igniter was installed.
The burners have an air intake adjustment to adjust the flames but I decided to wait on that due to the 10+mph wind. The flames are supposed to be blue and if the flames are yellow you can adjust the air intake to make them blue. I didn't know they were adjustable until I had the burner taken apart.
Hopefully I get to try the grill out this week...
is only 16 so I can wait a little longer to se if it goes a sixth generation. lol
just kidding, you probably hear this joke as often as we get asked when's the girl due here.
