  • Q:

    I HAVE A COLOR TUNE CARB MIXTURE KIT WHICH HAS A 12MM SPARK PLUG THREAD. I PRESUME THAT THIS ADAPTER FITS INTO THE CYLINDER HEAD WHICH IS 14MM THREAD, WHICH THEN ALLOWS ANY 12MM SPARK PLUG OR DEVICE TO FIT IN TO IT.
    THE ANSWER YOU GAVE BEFORE DOES NOT MAKE SENSE AS THE LARGER THREAD HAS TO 14MM AND THE INNER TREAD 12MM.
