Topic: What (else) is wrong with these carbs?

[edwardmorris]

OK, I will clean up the rest as soon as I can and look closely. Will post back soon. Thanks for all the help!

Alright, they're all cleaned up and I can barely see some numbers on two of the jets.

Needles are all K27201
Idles are all 40 (no K)
One where the float needle rests have a 20 on all of them (no K)

none of the rest have any visible numbers anywhere on them.

Where specifically should I look for the main jet size?

Also, two of the bowl and the jet holders on the bodies have this whitish powder that seems to brush off with a light toothbrush. Is it dried gas or something? Can I just wire brush it off or leave it alone?

they are probably just aftermarket main jets, sometimes they aren't marked quite as well.

you can get that white powder out of there, it's just corrosion or the last stage of gas going bad.  i would wear a mask or something, I wouldn't want to breathe that stuff.

But it would appaer that all of your needles are original kei hin, this is good.

Thanks Harisuluv, PM sent for all the pieces I need to salvage these.

I always wear safety goggles and mask when I use any kind of wirewheel, learnt that very early with my build dealing with corrosion, and how rotary tools love to fling needles at you.
