Stock carb choke tunning

Ive got a stock 2bearl carb on my 88 2.0l and im woundering what should my truck be running at rpm wise when the choke is on. Right now if i start up my truck (lately its been around 20-30° F) it starts right up and then sits at around 1600rpms for about 3-5 mins till it turns off then it drops down to 730rpms. To me 1600 sounds abit too high for me butwaiting it mightyou be spotweird on im just not used tothat high. If someone could let me know what thires is at and witch screw adjust the choke that be great. Thanks.

at startup it can run at 1600, but a tap on the pedal should drop it to 1200-1300 range. spray the choke linkage with gumout and see if the choke starts stepping down right.

that's exactly what it did ok sweet thanks
