welll i got ahold of the chinese people via sending messages back and forth on ebay. they sent me a new metering needle that was broke in shipping ( i was kinda hoping for a whole new carb, but i guess not)  and a few other small bits that attach to the needle. but the carb is sitting on my garage floor as i struck an ok deal on a weber and ive been running that. its a night and day difference with how it runs. i dont really see any power increase from it, but it does run really smooth, no more jerking from a lean throttle enrichment.
