Spark Advance and Throttle Levers become "sticky"?

[roccaas]

Saturday these two levers moved as they always have, Sunday they feel as of they've both been dipped in Elmer's Glue.

I see no binding at the distributor lever, no injury to any of the exposed connections, and the foot accelerator moves smoothly.

The car performs as it always has.

There is a real "heaviness" when pushing the levers up to the top of their arc. I'm guessing something in the steering shaft needs lubrication, or a piece has shifted, causing friction.

Weird!
