    Carb settings

    I have a 1965 289, stock 2 barrel carb autolite, seems to have a strong smell of gas like getting too much, but car is running very good, what are the bench settings for the mixture screws?

    The mixture screws only affect fueling at and just off idle.  Out 1.5 turns from fully seated is the standard answer.  Its a good starting point anyway.  Then set curb idle speed on a warm engine.  Then adjust mixture screws out to get the highest idle.  Reset curb idle speed.  That will be your best lean idle setting.

    Re: Carb settings

    Hello Doc , once i got my autolite rebuild with average gasket spare parts kits , is quite easy to set .
    Better if you search some pages about settings and set to oem standards .  The accelerator pump or springs can  be changed to perform better. 
    check the sparks plug to be sure you are rich .   Could be some carb  leaks , the gas smell you feel ?

    If you can smell gas, I'd check if the float level is set right and if there's a carb leak.
