Engine Mechanical problem
1978 Toyota Pickup 4 cyl Two Wheel Drive Manual 130k miles

I have a Ca. Dolphin RV with a 20R motor. I rebuilt the carb when it started to have intermitent idle problems. Now it starts on a cold motor/full auto choke, and hi speed is ok, but dies at 1000rpm or less as if I turned off the ignition. I have replaced all vaccume lines. I feel there is a idle circuit somewhere and I need help finding it.

Any ideas,
Jim

Did you drill out the air/fuel mix screw and clean that passage?
