Engine Mechanical problem
1992 Chevy S-10 6 cyl Two Wheel Drive Automatic 135000 miles

Should the butterfly always be closed or should it open when the engine has run for a while.I know on old carbs you adj the choke butterfly when the eng is cold and it will open as the car warms up. I am not familiar with this set-up, 2 barrel carb.
this one stays closed all the time except when rev'd up.

The engine normally started with just a turn of the key. Now the gas pedal must be held to the floor to get the engine to start once started it runs fine.

Appreciate any help, lost my job and trying to keep things running on my own.

I know on my carb I have to close the flap almost completely to get it to start, I figure its the same as a generator, even in the warm it stumbles. I just installed a manual choke line to the carb and I always close the flap on start up.

Was this
