broken-off air mixture screw

[pfo186]

i posted a thread on here a couple weeks ago about how i over-tightened my air mixture screw and the tip broke off and got wedged down into the carb. i think drewpy or houghmade told me a filed-down nail worked.

i finally took everything apart to investigate. i'm assuming the filed down nail is for sticking it up the small jet hole from inside the mouth of the carb, pushing the broken tip back up and out? the broken tips are wedged in there pretty good and i'm afraid the filed down nail will break before the tip gets pushed out. would heating up the carbs with a torch help expand the metal to get the broken tip out?

if none of this works i'm assuming i have to buy some new carbs?
anyone have some carbs for a 77' xs400?

thanks

you could try a little penetrating fluid in combination with a pick

no push down from top, it widens the hole slightly but it works and mine are still working. Certainly cures the lean mixture!

thanks guys, i'll try out your suggestions. keep your fingers crossed

i tried pushing up and all it did was bend over the tip

yea i ended up going thru about a box of thumbtacks(got 2 out of the 3 screws out), ans 3 6 packs before i came up with the internal press idea....

i used a #80 drill bit to weaken the stuck tips, and then they came out with a dental pick.
