hmmm....have you tried closing the outhole Sw during start up ?

Hopefully you or someone on the forums have the schematics? Continuous running score motors at start up are common for old EM's especially if they have been sitting. The problem can be one of many things, all easy to fix.

See below for repair and start up;

Did you wire brush the jones plugs? They can get a layer of oxidation over time.

Does the player unit rotate at game start?

That video is an example of what you should see and hear when you start a game. The flashing player 1-4 score lights is due to the (clunk-clunk-clunck-clunk sound) rotating player unit. You also hear it when the ball drains. Because the guy in the video is playing a 1 player game you hear the score motor rotating through players 2-4 to get to the next ball for player one (hope that made sense).

Is the Z1 (1&2 player score reset) and Z2 (3&4 player score reset) very top contact adjusted correctly? It is the one that sits on the very top of the switch stack above the plastic holder for the rest of the contacts. If the top contact remains closed when you pull in the relay it thinks the score reels are at zero even though they are not.

Free play is easy on this era Gottlieb. It's a simple switch on the replay wheel unit in the back box (this is covered in the Pinrepair documents too) There is a switch that opens when there are zero credits on the wheel. Bending that to stay closed even when the wheel shows zero, does the trick. Very easy to reverse should someone want the nostalgia of dropping a coin in the slot.
