CNG related problems

[doubletrouble]

city 2001 ....RPM drops when i turn ON A/C ..and seems that A/C is putting a lot of load on engine

[fyq]

doubletrouble!
just needs a visit to any workshop to adjust a/c idle rpms adjuster screw.

hammad!
do not let the rpms exceed 3000, means drive in higher gears with less acceleration to put least load on engine.

@fyq
first of all good work brother for helping people.

my query is when people says that their milage is 140 Km per cylinder, what exactly they want to say, i mean when get a full cylinder and then get it fully empty then count the milage? or when the red indicator switch ON then people count the milage, my car is giving 145 KM/CYLINDER with AC in City Islamabad, and fills in Rs. 350-380 mostly 380. its i think 55 l cylinder.

my second query is that, my car when starts after a long time i.e 8 to 10 hours, the engine after convert to CNG suddenly stops, and i have to start the engine again, but on the second try the engine try hard to maintain itself running on CNG, i feel like there is no gas in the lines between gas cylinder and engine and when i try second time to start the engine now the gas reach from cylinder to the engine but not enough therefore the engine hardly maintain it self in running position for first 2 seconds, then run normally. the second thing to be noted is that when i start the engine say after 2-3 hours then this problem is not occurring. plz help

santro lover!
thnx bro!
for milage, they calculate mostly till red and add some extra kms roughly.
its not like dat, cng is alwaz there upto the black round coil on the kit till we ignite it, and ur milage is very gud, and let it be like dat, just adjust its auto conversion to higher rpm, and clean up the plugs. ur problem will be solved.

sanamirza!

brother thanks for reply, what you think about that my problem is only occured after long time starting engine. if i start after 2 or 3 hours it starts normally giving no issue.

santrolover!
dnt worry, itsnormal. just adjust its shifting to high rpms frm any gud mechanic.

the metal pipe going to the throttle body of the engine from the cng kit is way looking cracked at the bottom of the kit, should i use silicon at that spot? i will also go to cng expert tomorrow to change conversion on high rpm.
