carb screws are buggerd.

[Pol Anorl]

wanted to take my carbs apart on the xj to inspect the diaphragms but 3 our of the 4 screws on all 4 carbs are knackerd, tried to undo and just minced the head.

Any idea on how i can get them off without killing them completely?

SORTED!!

Was on live chat and someone was like "just use a chisel" ..

2 days later i got bored and set upon doing my carbs then i remember what someone said (forgot who it was)

So i grabbed the chisel and got to work.
now i know what your thinking "oh no he didn't"
I used a junior hack saw to make a grove stuck the chisel in and turned it.

For some reason the chisel was far more superior than a screw driver and worked with every single siezed screw with minimum effort.

I suppose it worked better due to the more sharper edge and the broad handle got more weight on it.

So carbs all done all screws replaced and 1 diaphragm looking a bit tired added to shopping list.

Junior hacksaw and make them flat head screws. Dont go to deep as you run the risk of snapping part of the head of. You could also cut a cross and use a larger philips. Oh and go out and buy new screws. Get stainless allen head ones.

Only other option i can think of just now is cut away two sides so its flat and get mole grips on the head.

may have to do that tbh, didn't really want to take the carbs all the way out but looks like i probably have to.

if you have any needle nose mole grips you should be able to get them round the head and give them just that little bit of a twist.... I've used them on many a rounding screw and it works great

[andym]

Forgot to ask if they were still on the bike as I assumed they were off.

You might find you have to give it a couple of tries first though, and if the screws aren't too rounded then you should be able to use them again

Had the same problem on my XJ600n. The screws are as soft as putty. I got round it by using a small flat bladed screwdriver and tapped them round with a small hammer on the edge of the screwhead.(carefully).Got to use new screws afterwards obviously.

I got replacement screws and drain bolts when I did mine.

Had to dremel down a side part to get mole grips on number 2 and 3.

All the bits I needed cost about 21 quid.

There should probably be a sticky for this as it is a very common problem. The heads are usually rounded off because people use the wrong type of screwdriver. The tool required is a J.I.S. screwdriver and they are not readily available in this country.
Anyway as for sorting the immediate problem, you will need to remove the carbs from the bike. Once they are on your workbench/floor you should be able to remove the chewed screws with a combination of a small set of mole grips and an ill-fitting Phillips type of screwdriver.
The proper screwdrivers for the job are available from the link below:-

BTW Don't even consider putting the old screws back into the carbs.
Best of luck.

you can do this but it will ruin the screw (it doesnt really matter, like mentioned earlier, you would want to get new screws anyway)
With a flat head drill bit, put it in line with one of the crosses on the screws and hammer it on an angle (this will make an indent on the screw). After a couple of hits it will turn, and you should be able to get it out.

Had teh exact same prob today. 16 screws top and bottom all shit, rotten and painted on - never been loosened in 21 years. Used the hacksaw method with the carbs in a vice wrapped in foamy gear, found the biggest flat head socket wrench attachment and used plenty of wd40 and patience.
I say me, it was actually the missus who spent hours at it It took a while and I would have just tried to drill it out, but she done it ( how luck am I - a woman who can fix bikes )

Is there a good reason no one's mentioned trying an impact driver?
