Ever seen a gas gauge spin around like a clock?

I haven't either, until now.

I'm in process of "rehabbing" a '79 Scottsdale SWB that I got cheap. Pristine isn't the word that comes to mind when you look at it.

Anyhow, I spent the last several weeks pulling the top end of the newer crate engine it has in it down and repainting and putting everything back stock. Takes a lot of time.

That's done so I'm moving on to the electrics and instruments.

I noticed that while driving along, the gas "hand" as we call it down here in the south, is jittery, nervous and jerky. Sounds like some people I know. I don't mean the long travel back and forth our '73 always did when stopping and starting away. I mean the needle is never still at any time.

What tops it off is....most times when cutting the ignition, the gas needle makes at least two complete 360 degree revolutions in the space of a second or two, coming back to rest at approximately the right place again.

I wish I was making that up, but I'm not. I even got it on video.

Anybody have an idea what's behind that little scene?

Thanks...
