    Carb Screw Adjustments

    Can anyone give me a link to where i can find out what carb screw does what, i am sure its on here and i have used the search function but the list is very long, used to know them off the top of my head but its been a few years since i have touched one.

    Its not idling very well, having to use the chock to keep the revs up and when it does idle at around 1000 rpm its very lumpy, anyone point me in the direction to that would be great.

    Its also a bit over fuelled as i can smell that also.

    Thanks People.

    Big one on side is idle jet. You can take that out give it a good blowie and put it back.

    Tiny little one thats facing towards you upwards if your over drivers side is the mixture screw.

    Im not ya man to tell ya how to set up that though. perhaps someone else can help there.

    OK a question, if you adjust the idle screw which direction does what, clockwise it will do what and anti clock wise it will do what, i can not get it to idle at anything below 1500rpm for some reason, has been off the road for some time so i gues it may need a strip and re-build of the carb, runs perfectly apart from this.

    clockwise increase anti-clockwise decreases it.......you will prob find your accel cable is tight preventing it from going back to its fully closed position

    Thanks as for the cable its fine, if i put the choke all the way in then the car stalls, if i kep the revs at 1500 its fien, just if i drop the revs to sat 1000rpm it stalls and will not tick over.
