Adjusting idle mixture on 1920 holley

[MagnumMaster]

Can't see well enough to know what type of head on the set screw. Anyone know what type it is? It's on an 81 Cordoba slant 6. Seems to be pretty well hidden and deep inside the body.

Thanks

Should be flat head.

Sure its not a 1945 Holley?

My wife recently bought me a lighted up magnifying glass. Maybe a good idea for you to.

Geez,,, just realized today it's a Carter, not a Holley 1920!!!! Now same question, it's recessed so far back I cannot see what type of top or slot(s) it has. I might just take it off and check it that way!
