*It is quite often difficult to get the Phillips screws out of the carburetor float bowl. Those and a lot of other screws on Japanese products...are specifically Japanese Industrial Standard JIS 4633B-3/1991 and DIN/ISO standard 5260. Note the dot in one corner of the cross formed by the slots... The Japanese-style Phillips screwdrivers are available from [http://www.amessupply.com Ames Supply Company] and [http://www.katun.com Katun]... Using the normal American/European #1 or #2 Phillips screwdriver in a screw head with the dot on it will most likely strip the head on the first try.

A couple other options for float bowl screw removal: Take a Dremel and cut slots in the screws, then use a flathead screwdriver to remove the ridiculously soft metal screws. You may have to cut a piece off of the idle adjustment bracket to get at one of the screws.

Another, most likely easier, suggestion is to (carefully) put the carbs in a bench vice and remove the screws with an impact driver, BEFORE you strip them. Whatever you do, plan on replacing the float bowl screws.

The following is just a picture of the float. It's what controls the level of fuel in the carbs....

With that set, feel free to screw the float bowl back onto the carb. It's best to replace all the phillips screws with ~~Stainless~~ allen screws, as they're easier to work with (cost about $12 at Ace hardware to buy replacements). Float bowl screw size is M4 0.7 pitch, with ~~14 mm~~ length. Commonly written as M4x14 0.7 , although you may want to bring your old ones with you, just to make sure:

If you have to get slightly longer screws (say, 16mm), that will work fine.
