I cant get the screws off,Have the bloody phillips screw heads.Sits like welded.PLEASE ADWISE?

Drill them out? Thats what I plan on doing after I get some screws to replace them with. Otherwise try a hammer and screwdriver.

I sprayed mine liberally with WD-40, let them sit overnight, then went at them with my impact driver and rubber mallet. They all came out with no damage.

It wasn't easy to get a good hit with the mallet on the inner screws of carbs 2 and 3, so I held the driver bit with my Vise-Grips and tapped the end of the bit with a steel hammer.

When I put them back on I used allen head bolts with anti-seize. I got the bolts and the o-rings from Robert Barr.

spray them with pb blaster and let them sit over night. after that try to get a pair of vice grips on them . thats how i had to get mine out. replace them with stainless allen head screws , and save your self the headache the next time.

I used a battery powered impact driver with the proper size #3 Phillips bit. One impact and they were spinning out. Going in they got a good coating of anti-seize compound so a screwdriver will take them out next time..

A lot of time you can use an extension on your impact tool. A small pair of Vise grips work real good. If you can get one screw out you can hit the boot CCW to knock the other screw loose..

Drill them out?

And then what? Easy out? Retap?
Elaborate..

Once you drill through the head the boot will come off. Then you'll have a clear 1/4" of the thread left the grab with the vise grips. In most cases once the head is gone the remainder will come out by hand unless it is heavily corroded.

I removed mine with an impact driver and a hammer. I would only drill as a very last resort. Ya stand a huge chance of damaging something trying to get a drill in that tight area.
Use a drimmel to cut a large flathead slot and try an impact only if the head gets so mangled that ya cant get a phillips bit on it.

I removed the same screws on my 550 this afternoon after putting some PB Blaster on them last night. IMO, the key is to tap (ie. HIT VERY HARD) them if possible before using the PROPER philips head bit in an appropriate socket with a 1/4" breaker bar that enables you to get some leverage on it while you push on it as hard as you can. It wasn't ez but it worked for me on my 550 and my 1100 a few months ago.

Impact drivers are made specifically for this stuff.
Rocket science.

[oldgsfan]

Geez, and once you get them out, for godsake replace them with something that doesn't have a phillip's head. i followed the advice of other posters and swapped mine out for some allen head screws, though i hope to never have to mess with them again.

I did what was on bikecliffs website. I sprayed PB Blaster on them and let it sit overnight. Then I used a dremel to cut a line across the top of the screws and used a big flat head screwdriver to get them out. Any that I couldn't get out by hand I used my drill with a big wide flat head screwdriver on it. They all came out like a charm. There is also a link on BikeCliffs website to a guy that sells gaskets and allen screws (stainless). They're high quality, low cost and I was happy with them.
