    you cannot "feel" engine temperature by human touch for an engine.

    dear Xulfiqar

    thanks for your interest, well u r right, i didn't check it by touching, let me explain,
    as u know honda city idsi doesn't have gauge indication, it has lights green @ cold and red @ hot,
    before few months when i used to start my car in the morning green light used to take some time to be switched off,
    but now its switching off too quick,n water of car also reducing(not too much frequent) not even now, in winter too.

    the tappets are to make sure the valves can positively close off and compensate for expansion, It does not matter if the fuel induction is carburettor or fuel injection.

    Your car not having a temperature guage is a silly move by the manufacturer, You can see the engine temperature if you connect some sort of scan unit to the OBD port under the dash or use an infrared thermometer on the engine itself. If its heating up quick, your cooling fans will also start early.

    Is that hapening?

    your problem is quite different from mine, well i could suggest you to change your advancer and emulator, and make sure its air blockage in proper way, might be possible air intake problem is there that's why rpm fluctuating on cng only and pick up is not as much good as it should be..........

    do it on a dead cold engine

    symptoms of tight tappets:
    quick warm up(only few minutes of drive)
    misfire or car ka bhari ho k chalne
    after reaching honda 3s let it cool down or do the hot tappet setting
