hi,
i just got a 1964, williams, palooka machine. my friend gave it to me, i used to play this machine when i was 17! it was sitting for about 20 years, prior to me owning it. i replaced alot of parts and cleaned it up, and it is up and ready for play, except for some tweaking here and there. one problem i am having, is when the ball goes between the two passive bumpers, located at the top center of the playing field, and hits the roll over switch, if the 300 pt lite is lit, you will get 300 pts, then the next time 300 pt lite is lit you will get 100 pts, then 300 pts, 100 pts, and so on. i cleaned the advance stepper switch mounted in the cabinet, but it didnt do any good. what could be causing this???
