this is an older carb, i see a second screw that may be for air mix.

i'd look in the air cleaner side and turn the adjuster screw just above the wire holding the float bowl in, the screw with the spring around it.

this throttle stop should lower your slide as you loosen the screw, if the slide isn't dropping to totally block the opening, there's your issue.

extra air, Eg: vacuum leak is the main reason a motor is able to throttle up uncontrolled.

eliminate the carb. adjustments first, then use the link above to isolate any vac. leaks.

maybe someone can pitch in the second screw's purpose and proper adjustment, as my 1/17/114 lacks that.
