Thanks to all your help on this website I've resolved most major issues on my machine.
For anybody that might be googling in the future, I wanted to write the following here: One issue which i don't see the solution for anywhere online was my 3 spinning discs suddenly started to slow down after playing for a while. If i stopped playing for a while it would pick up speed but go back to slowing down and then just wouldn't move at all. I googled a lot and the closest thing I found was this thread with no solution:

I messaged bigsepe who thankfully is still a user here after 10 years and he told me to tighten these 2 tiny hex screws that connect the motor to the spinning discs. I immediately took it apart and followed his advice and it worked! Big thanks to bigsepe.
All that said the one major issue that i have not been able to resolve is the cellar kickback. It releases the ball about 60% of the time and when it does its often very weak. Maybe 10-20% of the time you get a nice solid pitch to the left flipper. I took apart both scoops, cleaned it out well, replaced the coil sleeve, and replaced the spring. Every time i put it back together it seems to work for a little while but quickly goes back to its old ways. I'm thinking its maybe a bad capacitor but im having trouble figuring out which cap to check.
The manual seems to indicate that the kickback is solenoid 14 which is tied to transistor Q7 but the schematic actually seems to show it going to Q4. Either way im still not sure which cap it goes to, C5, C6, neither or both?
Whats the best way to test a capacitor, set to continuity and compare readings? Do i need to remove them or have the machine on to test?
