Problem with my blaster not idleing when cold when the choke is on. Once it's warmed up it idles great with the choke off. If I choke it while warm, the engine will die. I looked over the carb and checked the adjustments and everything seemed okay. But I did notice that the tors is loose and moves side to side with ease. Now I'm not familiar with a tors and that's my question, is the tors supposed to be loose to compensate for throttle adjustment?
