Soak with some WD-40 or PB Blaster and try some channel locks or vise grips on the sides of them. There's also a method using a flat punch on them, but I had good luck with blaster and channel locks. After you get them out, bring them to Home Depot or Lowe's or Ace Hardware and repalce them with some stainless instead of that crappy brass. Four new screws would cost like $4 for stainless...I wanna say they were M4, but any of those stores should have a thread checker. Probably wouldn't hurt to replace the ones on the transient enrichment valve cover and the ones on the float bowl...

I've tried WD-40 with no luck although I'm not too surprised. I'm off to get some PB Blaster and will pray that the channel locks work. I've already managed to strip one pretty badly (so pissed at myself). Thanks again.

very common, the thread lock used is akin to the red stuff. very tough to get off. there's a ss carb screw set kit made up by motobuda? in the marketplace.

Squeeze hard enough to leave dents in the screw heads, then turn. And, yeah, I have sets of stainless steel socket heads screws to replace the stock ones. Bargain price.

If you've already munged up the screw heads, this technique might not be so important, aside from the fact it will get the screws out. I have an obsession (one of my many personality defects) about messing up screw heads, rounding of nut faces, putting wrench scratches on nearby surfaces, kinking things etc., so I was pleased to have been taught this trick decades ago by a mechanic that used to work on space equipment way back when. It's big advantage to me is that it will get the screw out without destroying the screw head.

I'll admit, though, sometimes this doesn't work, and you may have to resort to using huge pliers or vice-grips to crimp the head enough to put enough torque on it to get it out. Bye bye screw head,,....go to the parts store to buy replacement parts

Anyway,.. put the carb in a vise thusly:

Get a flat faced punch. A thick nail with the point filed flat will do nicely. Put the tip of the punch on the side of the screw head as shown in the pic. Tap the punch a few times. Then move it 90 degrees or so,.. tap some more. Keep moving the punch around as you tap and soon you will see a tiny bit of movement as the screw head moves from side to side. At this point, the thing is loose enough to unscrew.

I doubt WD-40 will do much to loosen up red lock-tight.

Also heat. A palm sized butane torch aimed at the screw head. The bolt gets hot and softens the thread locker.

But maybe the reason I didn't have problems with any of my carb screws was that I had soaked the whole thing in this overnight:

I have a little butane powered soldering iron I got at Lowes for less tha 15 Bux,, Take the soldering tip off & use it as an open flame, thats how I solder with it,,
A boogered up screw can be repaired with a pin punch & a careflully applied light hammer, the metal can be driven back where it came from,, &, the screw loosens at the same time,

WD40 isnt near the penetrating oil that Kroil or just plain Wintergreen OIl is.. I dont even keep WD40 now, since the propellant wont mke an engine fire off,, that stuffs about worthless, IMO. Unless you need Water Displacing spray,, then, its the berries..

Guys thanks for all the advice. PB Blaster and a pair of vice grips did the trick. I was ready to shoot myself for a minute. Thanks for coming through!

While an enormous pain in the ass for someone mechanically uninclined (word?) like myself, rejetting and doing the white spacer mod has turned sleepy Sally into a bike that's now almost deserving of being called a Savage. Throttle response is much improved, it feels peppier and even during hard 1-2 shifts there's no longer any backfiring.

For those interested, I used a 55 pilot (without bleed holes), 152.5 main, and 2 #4 washers in place of the white spacer. I have a HD muff and de-snorkeled using a stock filter/box setup. I have a K&N on order. Thanks again!

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
