i have the same zong 230 crf clone engine and i put a pwk32 on it but it was way too rich in idle and i couldn't jet it down enough.
all the posts on the crf230 forum say a pwk28 is perfect for the stock engine.
apologies if i am talking rubbish - anyone put me right on this?
thanks.

A pwk32 is way too big a carb for the stock engine. The pwk28 is a perfect match. I'm using a PWK30 on my Venom X22R but also have ported the head and 11:1 compression. Bigger is not always better.
