Try using ATF fluid. :) Your neighborhood will think there is a house on fire.

Re: Black smoke at startup
I'm thinking this may be it. It only happens occasionally and it
dissipates really quickly. It's just that when it happens it blows
what looks like a light coating black spray paint on the driveway.
This is usually as I give it a good bit of gas to start it in the cold.
The jeep takes a little while to run real smooth in the cold, but once
it gets warmed up it is fine. Like any other carburated engine I've
owned....
I may give the vac gauge a look and also check out the choke as
suggested.
Thoughts?
