How to increase CNG idle rpm

i have a honda civic 98 vti its on CNG.

recently i drove my car on a speed of 80km/h for 200 kms on motorway after that the car will not stand at idle on CNG. driving with AC is impossible at low speeds and the car cannot stand idle with AC.I FACE problems at trafic signals the car stops due to low idle rpm.

the car works fine on petrol.but the rpm needle on CNG falls down and the engine stops.some times the car reamains standing idle with out CNG.

Can any one tell me how to increase the CNG idle rpm to 600-800 rpm.
Iam ataching the pics so can any one identify the screw wich controls the rpm(race)

i also got my CNG kit serviced a month ago.

the CNG walas in my area are novice they just race the engine to red line nothing more.

Its not recommended to increase rpm from accelerator cable, as you marked in 2nd pic. Better is that take it once to your cng installer, watch him when he sets the idle setting, screw is on the side of the regulator/reducer, you have to get optimum rpm from there thats the best setting.
