The payoff lever is not working properly.
1. The arm that catches the ball does not rise all the way back.
2. The arm works fine when manually pushing it down - it pops right back up.
3. Having a ball on the lever arm is when it does not return to the top.
4. I've put rust actuater on the joints of the lever.
5. I've tried pulling the clip where the balls fall out of the jackpot ball channel and it doesn't help because the arm does not go down all the way.
6. I realize the general answer is that there's dirt in the joints but it moves very freely just not when in play.
It's a standard Nishijin (model C?)
I probably haven't described it well enough but could use help.20181001_165306[1].jpg
