The first time I took it apart I checked, cant remember the sizes but I am 80% sure everything is still standard - 128 I think. I will check that again this weekend when I get them apart. I know the needles are standard and not adjustable. I didnt look at the size of the pilots, it did look like the jets had been out before as there was marks from a screwdriver on them, and the screws holding the float bowls where quite chewed, so they had been apart a few times before.
