We've owned a Baby Weber 200 grill for a few years and I'm having a problem with a very low flame or sometimes the flame goes out. - Tank is over 1/2 full. - There is no adjustment to the regulator. - I've blown air throw the burner to clear any spider webs. - I've cleared the regulator 1. Turn off the gas at the propane tank 2. Disconnect the hose from the propane tank 3. Open the lid of your BBQ Grill 4. Turn all the burner valves to high 5. Wait for 2 minutes 6. Turn off all the burner valves 7. Connect the gas line back up to the propane tank 8. Turn the gas on slowly on the propane tank 9. Light the grill using your normal lighting procedures - I've searched here and the internet for other options. I love this grill, just need to make sure it's reliable. Any thoughts?
