frabulator

That unknown part of the carburetor linkage that causes it to hangup intermittently and for which bending, lubricating and all means of adjustment simply cannot remedy.

I was backing out the driveway when the damned frabulator caused a hang-up and I nearly shot across the street and up my neighbor's driveway into his garage door.

frabulator valve 

That part of the exhaust manifold system, on older vehicles, known as the heat riser and necessary to aid in fuel evaporation and make the transition from cold to hot idle engine operation efficiently.

The first cold day I cranked the old buggy over it was obvious the frabulator valve was rusted and frozen up as she wouldn't run right and carb touch-up adjustments made no difference.
