Yellow Haze Below the Carb?

[tcrave]

When I bought my gz, the people said that it had just had a complete tune-up, including the carb being rebuilt, but I have my doubts. People don't tell the full truth, simple as that. I have a large feeling that they lied about the entire thing. When I got home, it was having some troubles shifting, so I changed the oil and it was NASTY! I e-mailed the lady and asked if she had ever had trouble with shifting and told her I changed the oil and she emailed me back saying that no, she had never had troubles and then informed me the oil hadn't been changed in a long time and probably needed it. What the hell? I thought an oil change was standard in a tune up? O-well, whatever, I was expecting to be lied to, I just factored that into negotiations.

Turns out the hard shifting is normal for these bikes, either they don't have a first gear synchro, or it is out. Not a big deal though, just have to keep it in mind while riding.

Anyway, I now have a new problem. I was riding my bike down the street to work and all the sudden, it died. It was decently warm, so I tried to start it again and it wouldn't start. So, I pulled the choke level and it started again. I left the choke on the entire ride and then once I got to work, I turned the choke back off and the bike died...well dang! So then after I got off work, I started it up again and it would idle a little high with the choke on, and so I turned it to half way and it was still a little high, so I turned it all the way down and the bike died. So,I had to ride with the idle a little high and the choke half on. But, then after I let it sit for a day, its fine now.

But, here is the part that worries me too...I went to wash my bike yesterday evening and noticed a yellowish has all over the carb and on the metal casing right below the carb. I figured it might have just been a stain, but then I started scrubbing and with a HARD scrub, it started coming off...now I'm a bit worried. Any ideas?
