GE Cooktop - Flame Adjustment

Converted a GE Cafe CGP650 cooktop from Natural Gas to Propane (Regulator and orifices). Got it all connected and adjusted for low flame setting. All burners look fine at high and low flame settings

1) Does not seem to have much flame adjustment sensitivity when rotating from high to low flame until you hit 4 and below (1 to 9 scale). Then the adjustment is pretty dramatic. Is there anyway to make it more even across the scale?

2) Has a griddle function which ignites two burners (LF & LR) at the same time but range of adjustment is pretty minimal. Anyway to adjust this?

3) It looks like there is another adjustment screw to the left of the burner valve control shaft for each burner but it appears to be covered by a plastic shield of some sort. Any clue what these are for?

Was toying with idea of restricting propane flow at the source valve in the kitchen but suspect that is a very bad idea.

Hello vadar007. Welcome to the Gas Appliances topic and the Do-It-Yourself Web Site.

Questions 1 and 2:

Based upon what you're describing regarding the burner valves and the flame sizes, numbered settings, I suspect the valves are the multiple stage type burner valves. Numbers correspond to flame sizes. In that case not much can be done to alter flame sizes except by number settings.

What you see pertaining to flame sizes may not appear correct to you but in fact may be correct. You may have to adjust your cooking preferences and styles based upon the choices those valves offer verses the other type of non numbered infinitely adjustable flame size valves.

Those tiny set screws under the sealed cover caps must be left as they are. Bad idea to attempt to make any adjustments there. Those valves may be used on another model and not used on the model you have, etc. Not exactly sure what they are or may be used for but IMO without seeing myself in person, might best to leave well enough along if not sure.

Regarding your last sentence about restricting gas supply, you bet that is a bad idea.... Another condition best to leave as it is. Fully opened.
