perfect quadrajet cold start

this is a perfect example of what a properly set up quadrajet carburetor should sound like during a cold start. it's been between 20 and 40 degrees for the last 5 days, and I haven't driven the car at all.
this thing fired right up like new after sitting untouched for 5 days outside in temperatures below freezing, with only one pump to the accelerator. this is why I favor the quadrajet
