    get a complete engine service done, including new plugs+PROPER and ORIGINAL tappet settings for PETROL, make sure distributor vacuum advance is running properly, check for any air leaks into the intake manifold etc. etc.

    tune car for petrol first, make sure it gives good power and economy on petrol, that will tell whether engine is in good shape or not. Then change only timing for cng. And then adjust cng mixture. And ure dun.

    You should got check the valves of head. If they are vulnerble to change then get it change from some competent mechanic. Main indication of above conditions is as;
    1- RPM of car are not keep their adjustment after few days.
    2- Pick is low.
    if these conditions are persist, you should get change the valves and then get it adjust. You will notice improvement in consumptions upto desired level.

    ab4cd: First of all get your car tune up, changing spark plugs, throttle body servcie, empty gas fillied tank, remove oil from cng kit, change filter and add some blockage to air intake and use only syntheic motor oil (which is not so costly),all this will help you to get good pick up and milage

    It depends a lot on how you drive. If you drive carefully, you can even get up to 200 Kilometers in local. Instead of insisting on fixing the car, perhaps you can fix some of your driving habits and get much better mileage: https://www.pakwheels.com/forums/per...mileage-petrol

    A friend of mine owns an Alto, he used to get up to 130 Kilometers/Cylinder but now with a different driving style, he got 192 last time (local).
