It would've been so rare for that Genco to work just off of a dime. One question that everyone seems to ask me when I get a new machine was "Does it work?" That's the funniest question ever. The next question is "How much?" I'm like"How much time I have to put into this or how much money?" Money of course. No one thinks about the time.
I'm sure it will come out great. Take your time. Make it fun instead of a job. Just be careful of the backglass. I always have a fear of breaking it.
I only had one game that worked flawlessly when I bought it and I never had to make any adjustments. Even after 15 years of playing it. That would be my 1967 Williams Base Hit baseball machine. Everything else was gummed up.
