When I start the 340 on these cold days (not as cold as some of you guys out there) I sit in the car and hold the gas petal to idle @ around 1300 until the motor warms up or it will idle down and conk out. Once she warms up, it idles just fine (now that the motor is grounded properly, thanks again for the help straightening that out ) Isn't there a screw adjustment on an AVS that upon initial startup, you step the petal, turn the key, start the car and it would "fast idle" by itself until you step on the petal again, at which time it would return to a standing idle. Am I making sense here?

There is a screw near the intake on the drivers side, underneath the throttle assembly that is in contact with an "curved anvil" like piece that is attached to a piece of linkage the resembles a backward "C" connecting to a lever on the upper portion of the AVS near the bowl. It seems to be independant of the Throttle cable function. Am I in the right neighborhood?

Did the choke stat fully close the choke butterfly when you opened the throttle? 4953774-Choke002-Copy.JPG (66 downloads)

The position of my screw is on the same side of the step (which I see now, thank you for the picture) as yours, but no where near as far up the slope as your is. I will adjust to match yours, see how it goes and report back.

First thing to do is start with the car FULLY cold, remove the air cleaner and open the throttle. The choke butterfly should then fully close, if it doesn't you need to look at the choke stat. If it does adj the screw pictured in, I go more than I know I will need and back it off from there.
