Yes, I have the thumb throttle...but I am going to sell the carb whole with the cable and throttle and all. The quad is actually a 91 or 92, 'cuz it has that jacked-up dual-cable carb on it, so unless it's a whole system, the carb is basically worthless.
89...yes, I'd take less for it. -mail me your zip code and I'll check for what shipping will cost. I don't want to sell it for $15 shipped and then shipping costs me $20, you know? But I'd guess that $15 would do it.
