Help with choke on 86 Accord Carb

[Richard Quito]

Hello,

I'm new to the forum and need some help. Have an 86 Accord, original owner, carburetted model, 148K miles - normally, when starting the car, the choke sets the idle smoothly at 2000rpm. Past few days, it sets the idle at only 800-1000rpm and the idle is rough and jerky.

Does anyone know what to look for in this and are there any links to a repair procedure?

Please advise and thanks!
Richard
