I have two types of 24MM PWK carb, but which one is best? (there's only one way to find out....)
:bigsm:
1. OKO with a clear plastic float bowl
or
2. YSN with solid bowl and an extra small pipe from to of air inlet to body

I haven't used an OKO one but clear plastic bowls have been known to wharp with heat. The ones stamped YSN (I think that's the name of the Taiwanese manufacturer) are bgm ones. In my experience of copy PWKs, they are the best made.

If there's a diaphragm valve on the top of the bore it'll need blanking off. My bgm PWK28 had that.

Having said all that, IMO, save up your money and buy a Mikuni TM24, or a Dell'Orto.

The YSN has a jet coming from the air inlet, with a small pipe comoing from the bowl, is this a power jet? If so what does it do?

Yup, that's the power jet... designed to put more fuel into the airflow when going at full chat...
