Adjust the Choke assy and reset your fast idle cam adjustment to include the base idle

Can the choke be detached and serviced or is it a seperately replacible part
If it cannot be fixed do I have to buy a reconditioned carb ?

Suggested Repair

Adjust the choke assembly and reset the fast idle cam adjustment so it includes the base idle. The carburetor also needs adjustment.

Conversation Summary

The owner of a 1987 Toyota Carina AT150 with a 3A engine reports idle RPM fluctuating between 800 and 1500, needing to press and release the accelerator before starting, and idle sticking near 2000 RPM after a 15-20 km trip so the accelerator must be pressed to lower RPM before shutdown. One reply said the carburetor needs adjustment. An expert advised adjusting the choke assembly and resetting the fast idle cam adjustment to include base idle. The owner then asked whether the choke can be removed and serviced or must be replaced, and whether a reconditioned carburetor is required; that follow-up was not answered.
