    the original A/C idle up is very low down in the carburettor, compare it with the pictures on this thread.

    I closed (6) temporarily until I get to know the exact connection points.
    Have you completed all ur vaccum connections and what is the diff before nd after. Nd can you post the pictures of carby now after all connections are made as i also wants to connect em which are not connected

    Default New Mechanical Fuel Pump

    Today I have installed a new Japanese Mechanical pump in my Khyber.
    Bought from Kiani Autos for 2100/- Rs
    I already had the Solenoid valve used with CNG.
    Removed faulty electronic pump and relays.
    The labour charges have increased drastically.
    Paid 500 Rs for the fuel pump installation (The mechanic had to come to home)
    And paid 800 Rs for the complete carburetor service as the car was giving black smoke on petrol. The petrol consumption was also high. Around 9 kmpl.

    I cleaned PCV valve with carburetor cleaner. Suction test revealed that it is one side valve. In Normal suction, air flows with restriction. But It closes with a little high pressure suction. Is it ok?

    no.1 are float chamber vents, spray some in there, it will only work very slowly though, then spray some down the throats to dislodge any muck from the throttle plates and choke plate, after you are done make sure the choke plate works smoothly.

    @Xulfiqar Thanks for replying.
    @margallar The brake fluid level is slightly below maximum level but i didn't see any leaks around pipes and the circular black thing(the master cylinder i think?). I'll check and clean the pcv hose. If oil leaks from the air filter box i would see it on the small hole in the filter cover right?
