    Unhappy 4ac cutting out

    hey guys, being this my first real car, i having trouble learning to fix things hahahaha. anyway, not sure if all cylinders are firing, and the engine cuts out when i stop or sit in neutral. wondering if anybody with good experiences with a 4ac or anybody knowledgeable could come and have a listen/look. can supply some beers and a bbq or something, jsut would be great as being a UNI student, money is slow.

    regards in advance, Khai

    like ill sit in neutral and get it so its out of the flat spot and hold the accelerator on 2k rpm, it will rather quickly just go 1800..2000.1800.2000.1800..2000

    Checked Ignition leads? Distributor cap??? Coil ?
    Checked Fuel filter? Fuel Pump???

    no. i think one cylinder is miss firing. im really new to all this and no nothing, trying to learn from forum asnwers from people who talk like i know what they are saying half the time. hahahahaha. just put new ngk plugs, nothing. might try leads but they r newish. when i look at a jet inside the carby throat, i see it kinda of plurting fuel when in those flat spots.
