How to get these screws out?

[scrisp]

How in the world do you guys get these screws out without tearing up the heads?

On the other carb, they came right out with a screwdriver, but none of them budge on this carb.

Are you using JIS screwdrivers?

My JIS screwdrivers have a metal end on the handle, I will tap lightly on the end of the handle with a hammer, did I mention I do this lightly, I just keep tapping while applying pressure until they let loose

No, I was using a Phillip head screwdriver, but did just order a set of JIS screwdrivers. Do they really make a big difference?

Thanks, I just ordered a set for this. I'll try what you said. I just don't want to be trying to find those screws online if I don't have to.

Yes, they do because those are not phillips screws, they are JIS.
If they are really stubborn then an impact screwdriver can help too.


And make sure you are following this... The Seadoo Carb Rebuild Thread

I was just going to post a thread I am having a big problem as well. I tried the jls screwdriver then a # 2 Philips as it didnt have the little dot. Then heat from a tiny torch. Next will be a impact. Never had such a problem. These wont budge.

They are pretty far gone...
I would drill them just until the head pops off, not into the aluminum. This will allow you to get the valve block off then they will come right out with simple pliers. You will need new screws which you already do.

Small chisel and hammer. Pick a spot that is not close to the slots. Go about midways. Position the chisel at about 45 degrees and wrap it. It may turn. Don't let the chisel shear off any of the bolt. After you get a good raised surface you can use a 3/16" punch with the hammer to influence the screw and get it to move. Use some PB blaster first. It may help. the screws inside the carb... I use a center or prick punch to get them moving. I never heard of a JIS screwdriver till I started working on seadoos. LOL I do have them.

I've heard people using valve grinding compound on the screwdriver tip but I've never really gotten serious with it. I'm going back 50 years I've been removing screws with the method I use. It works. Good Luck!!

NOTE you can also try an impact drive but I never had much luck with those... especially on aluminum.

Impact screwdriver is what you need like Mikidymac said.

Thanks everyone, I received the JIS Screwdrivers and the screws came right out.

I got a really nice set of 4 that took care of everything for $17 from Amazon. Well worth the price.

If you have a problem like this again but worse, here is a trick that worked for me when I had screws that were completely stripped round inside. Take a pin punch and drive the screw heads back into shape as much as possible. Usually the screw head material is still there and can be punched back into the stripped hole. Then take an impact driver and drive it into the screw head. it will reform the screw head to the bits shape and crack them loose. I don't advise reusing the screws, but I was able to reuse the screws after this process.

Lucky. I paid much more for those special screwdrivers. I even bought an impact type but... I'm not much of an impact guy. Usually just strips the slot. Glad you make out OK.
