RE: Gremlins knocking on cold start

[Preferred Customer <gpowell@acacianet.com>]

I've had a mysterious random knock on cold start-up and wonder if anybody 
has some insight.  It's on my '88 80q.

Poking around under hood at cold start, it almost sounds like the noise 
is at the rear of the engine, the distributor maybe?  If so, why only at 
dead cold?  And why did it go on a month's hiatus after above said work?

Distributor. At least that's what is wuz on my hi-miles 85 ur-q. Dunno why only when dead cold, but I had the identical symptoms and replacing the dist cured it 100%
