I just replaced a potentiometer on one of the left hand burners (it works now) and put in the new gas simmer controller that was part of the kit. My right front burner was putting out very little flame so I also replaced the jet assembly for that burner. Now it flames up high with lots of yellow flame but it is a "lazy" flame--the gas doesn't seem to have much velocity. Is there some way I should adjust the flame? Thanks for any help!
