    Dear Carter experts,

    I am currently restoring my Carter AFB 3826S (1965 4bbl carb on 300cui).
    Stupid as I am, I managed to destroy one Idle Mixture Screw. Don't ask. :spank:

    I could locally source replacements that are meant for the new Edelbrock carbs. From posts on this forum I understand that Edelbrocks are essentially the Carter design.
    Will these Idle Mixture Screws fit?

    Thanks for your help

    Patrick

    edit :

    the parts they are sourcing for you - probably edelbrock #1496 . about $8.00 at summit . you can go to www.summitracing.com and search "EDL-1496" and it'll come right up for ya and you can check it out . i think the old carb may be an OEM pontiac ? left rear fuel inlet . maybe i can get one screw out of that . miracle .

    Thank you. They look superidentical.

    The screw I ahve has an overall length of 37mm, i.e. something like 1,45inch
    The "needle" alone is 21mm= 0,83inch
    diameter of 4mm=0,16inch

    Does this match with your Edelbrock?

    edelbrock part #1496 looks like pic above . older versions are just regular screw heads and these are screw/torx combo heads . and the older ones i have do not have a taper between threads and tip . measurements were pretty close both ways - i'll list "torx" style .
    UHL ( under head length ) : 1 1/2 inch - 37.83mm
    threads : 5/8 inch x 3/16 inch ( OD ) - 16.19mm x 4.65mm
    tip ( not counting taper between threads and tip ) : 5/8 inch x 3/32 inch (OD ) - 15.83mm x 2.50mm
    there ya go . as good as i can measure .
