How to get these screws out?

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
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.

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.
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.
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.BrianMoore

A favorite of mine for carb screws. I keep one of these on top of my workbench as my go to screwdriver. Both are worth the price.
Next time (and there will be a next time, always is) before starting, wrap the "work" in a heating pad & give it a couple of hours.
I've' used in this order for years with amazing success if on a before known "pia" fastener(s),
*chemical advantage
*thermal advantage
*mechanical advantage, if need be.
Most times the chemical/thermal would suffice. (Keep cold spay in your arsenal, it introduces exponential difference in thermics)
You got one shot to get it done right the first time so use all these advantages before hand on known pia fasteners.

buy a small tube of valve gringing compound dab a little compound on philips screw drive put screw driver in screw tap the screw drive with hammer slightly and turn the screw out ( old mechanic trick) the compound will grip the screw driver end to the screw BAM !!!!
I'd try a pair of channel locks on those. A variety of tricks. My goto method is a chisel, hammer, and a 3/16" pin punch. The problem you are having and we all have is the reason I put waterproof grease on everything when I reassemble. When you look at my carbs the right way they
