Picked up a huo GP today, very rare, but it looks to be every bit huo. Guy has had it since 1979 and it has 7500 plays on it. Nicest game I’ve ever seen. Everything works on the playfield, but it has a player and ball count issue. Start a game and it’s immediately on ball 2, then plays through first three players despite only pressing start once. After it gets to player 3, it then goes back to player 1, where it seems to stay and never advances to next player or end a game. I am not an em guy, and could use some help where to start. I shot a video. Thanks for the help.
