Hello I'm a new rx7 owner. I'm rebuilding the carburetor and was wondering if anyone has advice on seized bolts. I've looked on Google and I've tried liquid wrench but this bolt is absolutely stuck.

Here's an image of the bolt in the carb if anyone has had experience with taking it out

I had the same issue. I took it to the service station with which I deal, and the mechanic used a whack it with a hammer screwdriver tool (I'm sure it has a proper name) and it came right out.
I reassembled with new screws.

I've had good luck getting screws like that out using a vice grip.

Pick a set of vice grips that have nice sharp teeth.

Then set them so that they bite the head of the screw as tightly as possible. You want to really squeeze down on that bugger to get the vice grips to lock and dig into the screw head.

Now bite down on the screw head with the vice grip positioned on the screw at 90 degrees, with the jaws of the vice grip flush against the carb body.

Now carefully torque the screw head counterclockwise, it should let go. And the screw can be reused.

I cant find your pic buy if the Phillips head is kinda stripped and you cant get a bit to grip well . this is for before it is all screwed up take a tiny center punch or even a small nail set , place the tip right down into the bottom of the star and give it a couple nice sharp cracks not hard just good and firm . What this does is stretches the head of the screw enough that it will usually come right loose , it might even be loose when you try ,, try it you will be surprised how good it works .. Lots of times if they look a little shitty I give them a little crack before even trying to get them loose . ,, If they are already screwed then the vise-grip option is probably next in line

Only use a sharp flat head on the Nikki screws.

Cookboy has the right idea. It's called an impact screwdriver and is the only tool you should use on this screw and one on the other side the first time you're loosening them. Forget about the vice grip, and good luck getting one in that limited access area anyway.

There is another evil screw on the other side of the carb which holds the choke pull-off. Do you have to take it off too? Well, I wouldn't take off the screw you're struggling with right now because it's not necessary to take off the air horn. You'll see. Neither is the other screw. If it's just a basic rebuild you'll be keeping this stuff anyway. But you asked so I gave you an answer. Impact screwdriver.

I may never use it, but then it may save me another trip to the station.

You'll use it. That's one of those "only once in a while" tools that's worth their weight in gold. Saves so much time, effort, and frustration.

Needed to borrow one to take the little itty bitty teeny tiny Philips screw out of the brake rotor on my DD Honda Pilot. Had struggled for 30 minutes with a hammer and regular Philips screwdriver, then used this and two whacks it was out.

"Forget about the vice grip"

Now Jeff, some of us folks don't have the cash flow to go out and buy a special tool every time we need to get something done.

But we sure as **** have some vice grips in the tool box.

I'm telling you, it works. I've removed many a Nikki screw with the grips when they don't want to budge, even the ones in the tight spots.

Thanks for all the tips guys. I got it all disassembled with the help of a technique shown by the mechanic I bought the car from. Just hitting the bolt's head at an angle using a hammer+screwdriver did the trick. Hopefully rebuilding the carb fixes the idle problem it had when I bought it a few days ago. It dies unless the choke is on or I feather the gas.
