Well, I got the clip thing for the big spring in my carb, but it's still doing the "quarter to half throttle open then die" trick it started doing yesterday. So, I set the idle mixture screw to 1 1/2 turns out, and it wouldn't even start. I got it to turn over once, but that was it, so I backed it out to two full turns out, and it started right back up. Once again, it wouldn't let me open the throttle to any real degree (even with the clip correctly in place now), so I pulled the carb back off the bike to check it out as per Mr. Motolab. Here's to hoping it isn't anything major.
