Is it blue oil smoke? or is it black , sooty smoke?

My truck sputtered and backfired and blew black smoke shortly after being revived from a 5 year slumber. It turned out to be a faulty accelerator pump in the carburetor leaking fuel into the intake and not giving enough fuel when the throttle was pushed.

I thought for sure I had an ignition or timing problem at first but everything in that department checked out.

Rebuilt carburetor did the trick.
