    That's one shit sentence.

    Have a look here:

    You should be able to find a diagram for the carby on a 4ac. It will point out the idle adjustment screw and give you instructions.

    There will be a throttle return screw which needs adjusting. Take off the air filter and housing and look at the back of the carby facing the firewall. You should see the throttle linkages there. Play around with it and you will quickly find what you need to do to adjust the throttle return screw.

    He is Japanese and translated it to English.

    "That of which the idle is raw and high above the top, bringing down to 1000rpm. Bid with confidence."
