I bought a 2 burner Silver A from CL.
It is in great shape, about 5 years old.
The problem, the back burner takes a good 5-8 minutes to light up.
If anyone has any suggestions, I would appreciate it.
Sounds like the crossover tube is partially blocked by junk the BBQ heats up the junk softens and lets the gas through. A good clean internally should fix it.
