thermowax thingy
is the thermowax thingy supposed to extend or retract when hot? i pulled my TB off over the weekend, and i thought i adjusted the cold start. i screwed the screw all the way in, thinking that it would idle at about 1100-1500 when cold and drop to 750 a lot sooner. but now it idles at 1600 all the time, cold and hot. i dont understand why it never drops its idle, if anyting the idle should be lower. i cant pull the tb off again till the weekend and when i do i plan to either eliminate the cold start completely or set it back to the way it was before

The thermowax retracts as it gets hot. Just adjust your set screw as shown in the FSM, and you should be fine. I belive, in the '87 FSM, they actually list the tempratures that the two marks on the fast idle cam relate to.
