I've actually had good luck with Zama carbs. It just irritates me that the kits cost double what they do for a Walbro.

The real junk carbs are the "Rui Ing" carbs... I have made some money off of them though. I had two "Mini Harley" small chopper motorcycles given to me because the owners were disgusted with not being able to get them to run, or run consistently. I took the Rui Ing carbs off, put a Zama on one and a Walbro on the other. They then ran great, and I sold the motorcycles for 200 bucks each!
