Even when new IF they sat for awhile, a week or more, you would have to crank them for awhile.
Way back when they were a newer car & more than likely a daily driver so you didn't run into these problems.
AGAIN, I would rather crank it over for awhile to get oil flowing RATHER than a dry start.
Todays fuel with alcohol evaporates even faster with the normal heat of the engine.
