Uneven flame adjust

Clean the burners

Mike, do the flames look to be normal size once they do light or are they very small? You may have a bad regulator. The regulator is used to lower the incoming pressure to a safe level to prevent excessive flame size. It sounds as though the regulator is not working properly. However, if the flames are small or uneven levels, check the orifices directly below the caps or on the burner valves for any obstruction such as spillage or cleaner residues. You can replace the regulator with any brand that has a 1/2" in/out pipe thread. Most are available at a large hardware store.

if they work and light your stove then leave them alone,

Are the burners uniform around top? Pictures show that there is a slot on one side. The tech is probably right.. You are not the only person complaining about this. Call back and see if there is a different burner that will fit you stove.

I have a GE Model Cooktop JPG337BEJ3BB and the burners are flaming to high. How do I turn them down?

if you look closely, down the center of the knob ther should be an adjustment screw to lowert he flame

Hello
The soot stains come from the air mixture, that will show too much yellow flame tips, just adjust the air intake, too have an idea how much to adjust it, and also it wouldn't hurt to clean the flames holes by sticking a pin. Alos make sure you have the right fittings converters. It's the grill LP Gas or Natural?
Hope this help

check all holes on burner make sure all air/gas holes are unclogged do not use any ajax or any cleanser that will leave a powdery residue.

Remove the burner knobs, inside of each shaft is a straight slot screw adjustment, use a flshlight to see it. Sears has screwdrivers this small.While holding the shaft with a pair of pliers turn the screw in the shaft, it will be hard to turn, this is normal.
Continue doing this until you obtain the desired flame setting.

there is a bypass screw on each gas valve. adjust so flame is reasonable when each burner is turned to low
