81 toy carb issue

[shane416ex]

I hit a big bump at work yesterday after work in the quarry, the left front may have caught some air. As soon as I did, the truck quit idling. It will run with the foot lightly on the gas. I got her home, started it this morn and she fired right up until fully warm and she died again. I'm going to tinker after work today, any thoughts on a good start? Seems like an obvious carb issue. I'm not a complete idiot, just was looking for potential insight. 1981 Toyota, bone stock.

Hi all,

I don't know anything about the stock Toyota carbs that came on the 20/22R engines, but on the Aisin built carb on the 2F (Land Cruiser) engine there is an idle solenoid circuit (IIRC.)

At the base of the carb, firewall side, a wire sticks out of the carb. This is the idle solenoid wire. If it becomes disconnected (or fails) the 2F won't want to idle.

It is a long-shot, but maybe take a look on your Toyota carb.

Good luck!

Alan

Yup, IIRC there is a solenoid.

yes the idle fuel cut solenoid. iv never had one fail on me but if you unscrew it from the carb there is a little o ring on the end of it. i have had issues with those. if the o ring gets tore or has a flat spot the symptom is the truck wont idle well if at all and it will die every time you come to a stop. unless you keep your on the gas.
