What should happen on power up is that it checks to make sure there are
balls in the subway to be fired from the canon as need be.
If there are balls in the subway when you power up, the canons should
swing out and then back to test the limit switches.
If there are no balls in the subway, it will fire a couple of balls down
there. If there is a problem with the optos, it may keep doing this.
That's my understanding anyhow.
Clean your optos in the canons, and under the canons in the popper area.
Put the game into switch test and make sure all for a good and not
intermitent.
If your right canon isn't moving at powerup, I would also check the
limit switches under the canon.
