I’m trying to rebuild my carburetor for the first time, but there are one-way screws that I don’t know how to undo. I’m pretty sure I’m supposed to unscrew them because the plate they are holding down has a gasket and my rebuild kit has that same gasket. I just can’t undo the screws to replace said gasket. Any advice is appreciated.
Yes. You aren’t supposed to be able to get in there. Your supposed to toss the carb, and buy a new one from the dealership. This is so you can’t get inside and adjust anything to mess with emissions.
However you can remove those fasteners, you’ll have to cut a slot in them with a Dremel ideally and use a flat head to remove.
some carb rebuilders don’t want anybody in that cavity…
there are 2 adjustments that are critical in there…
the accelerator pump height adjustment and the metering rod lifter adjustment…
i am hoping you did not soak that part in carb dip… as that will destroy the plastic pieces inside…

as for getting the one way screws out…
do you have a flat screwdriver… how is the end of the screwdriver… you can sharpen it flat… so it digs into the ramp of the screws…
you can also sharpen it like a flat left handed drill… so it has a sharp edge that will dig into those ramps… sometimes you can use a sharp chisel to make a mark to allow the screwdriver to catch…
