I find it strange out of all these posts, not one word mentioned about using a little impact driver,.....when in reality it would have done the trick right from the get-go ! If you don't have one, get one.

I know, it hard to use an impact driver w/o removing the carb from the engine. But once its off, an impact driver is the dog's bark !....or is it the cat's meow ? Shocked

be sure to support the tab the screw is on or you'll break it off with the impact driver. Grin

maybe why no one's mentioned it. Cool

Very true. Impact drivers can be brutal. Besides, with soft-headed screws like these that are, in effect, welded to the carb body, using an impact driver will make quick work of the screw head -- it'll look like you took a drill bit to it. Been there, done that more than once Sad

Then, your last resort is to dremel (or chisel) a slot in the head and use a big fat flat screwdriver with vise grips on the handle and a 310lb buddy to push down on the screwdriver while you put the torque on it with the vice grips. Tongue

Call me crazy, but I use RTV.

The real benefit to loctite is to seal the threads so they don't come loose from increased clearances due to intergranular corrosion caused by the different metallurgy of the nut and bolt. It is not primarily used as glue.

RTV seals the threads too, and sort of glues the threads, but it never bonds so hard that you can't take it apart later. It has pretty good heat resistance (especially the high temp type) and it keeps anything it is on from rusting.

RTV is WWWWAAAAYYYYYYY cheaper, too. Kinda messy, though.

If you got vice grips... and the head is still on the screw... whadayaneed a screwdriver for? Just use the vice grips on the head.

One normal progression for these situations is:

1. Try real hard to get the phillips head screw out with a screwdriver.

2. Utter a few expletives about the stupid f***ing screw that now has its slots rounded out.

3. The set of vise grips you have weighs about 5 pounds and is more suited to working on bridges, but one works with what one has, eh?

4. You clamp the vice grips on the 1/4" diameter screw head, partially crushing it, but that's okay because you want to get a good grip on it.

5. You start to move the vise grips counterclockwise (right? Undecided

). It just starts to move, and SPLING!!,.. it lets go of the screw, leaving the screwhead looking quite mangled and shaped somewhat like an upside down cone.

6. You reapply the vise grips, further deforming the head but you are not dismayed because you will toss this screw once you get it out.

7. SPLING!!! the vise grips pop off all by themselves.

8. The screwhead has lost about 2/3 of its mass. There is very little left to grab.

9. Find the dremel tool, cut a slot in what is left in the head, and go find Bubba.

10. Apply the vise grips to a big fat screwdriver while Bubba holds the screwdriver down in the slot. Torque out the screw.

11. Give Bubba a beer.

OR

Skip steps 1 thru 11,... Use a little heat and a flat faced punch, and jiggle the screw loose so's you can back it out normally with a screwdriver. No expletives, no beer for Bubba.

Sound advice, based on two time-honored axioms:
1. One must know one's limitations.
2. One must maintain an awareness of the big picture.

I actually said I WAS able to get them off with vice grips after spraying the crap out of them with PB Blaster. I tried before without it and couldn't get them, hence the post.

The sad reality is that an experienced person doesen't have a problem getting the screws out. The very simple trick is to not let the heads of the screws get messed up in the first place ! The second you've let a screwdriver slip on a screw, you have not only made a mistake, but you have also shown gross inexperience.
And I get tired of hearing about the "soft headed screws" These screws are no softer than any other mild steel grade 3 screw. But it does make for a good excuse for the inexperienced.

I wrote a post on how to get carb screws out w/o damaging the screw heads,......lotta good that did. But in short, the simple trick is,....apply enough pressure to the driver that it has no chance of slipping ! If you find there is no way of doing that, you just made your first mistake.

If there is any resistance when removing the the screw, and any suggestion that further attempt will destroy the head - it's not Phillips, it's JIS - I move on to Plan B. That involves using a Phillips bit of the correct size mounted in my electric drill - in reverse mode. Downward pressure and the sudden impact quickly removes the screw. On the odd occasion I've damaged the head doing this. Plan C is the same, but with the drill in forward mode. This never fails, since the shock breaks the head off of the screw, and the remaining stud can be removed with your fingers. Works for me.

Yes, you can "sculpt" the metal around the slots back into place, but it only looks nice, it is not back to original strength. I have done this many times to hide my hamfistedness with the screwdriver.

The metal you pushed back into place, though, is just a trifle stronger than pudding.
