SO....now that I know for sure what is broken....I'll tell you to keep chuging away at it with the drills, and being very careful not to mess up the threds...
That is the Idle/air/fuel mixture screw
Length of the threds 1/2in
length of the tip ....(pointy end) 1/2in
I understand that you like to use an esy-out, BUT JMHO, this job is going to be a drill, and pick job.
From what you have said, I'm thinking that you still have at least 3/4in. of the screw, left inside the hole!!!??
Start with a 9/64 drill to make a pilot hole(Centering), then step up to 5/32,...then up to the max size of 11/64!!!!!! When using the 11/64 in the hole, make sure NOT to wobble the bit in any way......(If the threds are stripped out,....you will never get the tap to make the right size threds!!)
After removing the screw/debrie from the hole, using a 10-32 unf tap to replentish the threds.
If all goes well....then wash out the hole/threds, with a lite oil and compessed air.......then...hand install the new screw....then wash out the hole,again, and if ya did it right.....ya just saved the carb......IF NOT....then the carb throttle body,
is pretty much useless, with 0ut an Idle air screw!!!!!!
Left handed drill bits are avail. form Harbor Frieght, and work lots better than righthanded drill bits, for this kind of work........(Just a thought)
Hope all goes well for you!!! NEED MORE HELP.....Post back!!!
