i have a charbroil 'red' grill. it used to get very hot. now I hold my hand over cooking surface for 5 to 10 seconds. not good.
yes i tried to reset the regulator based on most internet suggestions
i see nice blue flames coming out of the tiny holes but they are only about 1/4 to 3/8 inch in length . moving knobs from low ot high seems to have this small effect.
yes, there is a hairline crack on the gas tube (its acts like extra holes i guess in that blue flame comes out of that too)
Should there be much larger flames at high setting?
