Engine loading up?

[llwood]

So when i start the stang i don't get any smoke, but if i let it sit there and idle for a while when i get back in and blip the throttle i get a bunch of smoke??? What gives, i thought maybe it was just getting loaded up on fuel or something cause it only does it after idling. Anythoughts? Oh yeah 86 lx EFI
