Okay, been researching and I'm pretty sure i have clogged idle jets. Here is a quick summary from another forum user (with their permission) of the problem:
The throttle plate is held slightly open when cold, then is allowed to
close as the engine reaches full op temperature. This means the idle
jets don't control idle until the throttle is fully closed, which is
just about the time the car stalls.
When the OP holds the throttle open, he is shutting down the idle jet
and using other fuel delivery paths, which are not blocked.
If plugged jets are in fact the problem, some compressed air down the
idle speed screw hole should cure that fairly cheaply. Clean the gum and
sediment out of the float bowl as well.
Could anyone give me an in-depth explanation of how to access these idle jets? Ive read all over that they are the issue. Also, my dad and i thought it was the float, so we were going to buy a carburetor rebuild kit, but i would love to be able to fix this for free. Also, i noticed someone mentioned something called seafoam for cleaning their carburetor; could anyone tell me where I could find this, and is it effective?
