Brother RPM was abnormal. Autochoke was fine when engine is cool goes upto 2500 after sometime if we turn the engine off and restart comes back to 1.1 if we press gas pedal goes upto 2.5 again ,without ac sometimes RPM is stuck at where is should be when engine is cool. other thing if we press Gas pedal fully and release it quickly rpm comes back to normal again if we press it goes upto 2.3 2.5, with ac it was fine comes back to 1.1 - 1.2, with ac off it behaved abnormally, plus on AC RPM was dropping, now with AC RPM is fine @1.2 and without it is 1.0....
Found an experienced guy who did well with vacuum pipes and AC Solenoid, he said he disconnected Autochoke bcoz it was faulty,will be replaced as soon as i could go to Rawalpindi now RPM is fine rises when ac is ON and comes back when ac is turned OFF, just auto choke doesn't works.. so i have to press gas pedal for a minute and two in the morning...
