With two carbs, surely there are enough parts not messed up to make one.

Oh man, I would have never thought it was that simple!  That's great, though.  Super easy to work with.  A GOOD pair of vise grips - off brand Craftsman or harbor freight ones are worthless - Irwin Original vise grips will squeeze that and let you get it off.  I, personally, like my Prograbit easyouts, and in a spot that accessible it would be just too easy with your drill.  Allen headed screws are the best replacement, as was mentioned.  I picked up flat black steel ones from my local Ace Hardware for maybe $3.  I should have got stainless; the black ones eventually rust.  A drop of blue loctite on there and they'll never back off.

All of the screws that came on this carb are notoriously soft.  They are all easily stripped if there is any binding.  Penetrating oil, a little heat, and the persuasion of some other tools should help you get everything apart.

Your mechanic sucks. You're doing a better job than him. Good work.
If you have a hacksaw handy you can saw a slot in the head of that pesky screw for a flat blade screwdriver to fit. Don't reuse that screw tho. Otherwise,vise grips like they said. Be really gentle if you mount the carb in a bench vice to hold it still. It's easy to distort a carb body by overtightening in a vice. Then it truly is scrap.
Hope the bowl screws give less trouble !

Sorry for the long absence.
I had a death in the fam last week.
Also, it has taken about a week to remove the many stripped screws.
So, on the newer carb:
I got stuck trying to remove the screw that holds on the plate holding the valve in place.
I got frustrated and gave up before my morale was crushed entirely and went back to work on the older of the two.
The older carb:
I have removed all but the throttle (due to the stuck lower screw) and the smaller diaphragm set up on the side. My valve is scratched up pretty badly on the side. I couldn't get a clear enough pic to further illustrate. It looks like someone just went at it with the needle nose pliers. I know i have the other carb but I really do not want to have to fight with that screw. Is this an issue that needs to be addressed now? Should i replace it?
At this point, everything that I have pulled looks ok. I am intending to clean my older carb, put it on, and try to start it and then, if necessary, disassemble the newer carb.
The screw holding the valve plate in place is one reason(took a wk to get it out of the older one) but i also know that i am looking at an uphill battle removing the idle mix screw in the newer of the two.
Still, if it's worth doing, it's worth doing right.
Patiently awaiting advice...

No worries! Feel better.
I took a hammer and a flathead to that stubborn choke screw and am now prepping to soak. Auestion: looking down into my diaphragm from the top of the carb, i can see some gunk around the metal plate inside(holding the needle in place) should i renove that for cleaning? The screws are small and pretty far down. I didn't want to risk stripping them uneccessarily-or could i switch it out for my other carb's diaphragm?
Still need an answer on the scarred valve. It's scratched along the upper edges. Probably from someone fighting to remove either it or the plate screw.

Thanks,

Jaye

unless someone drilled it out to be a 60, I would guess 55.

but you got two carbs, what's the other one?

MY... what big eyes you have grandma.
