I just drained my CNG kit and cylinder with oil, and i make sure not 1 drop left in kit n cylinder.
but when i fixed back everything and started car after verifying there is no gas leakage. It was not smooth on idle, than i adjusted the knob for idle speed on clockwise n now it seems to be fine.
Should i go to mechanic for CNG proper tune up or its fine.
and also, my 1000cc Santro gives me 135- 140 Avg on full cylinder. Is that fine ?
