Quoted from orlandu81:Thanks everyone for the support! Funny to know that this is a "starter" pin and I had no idea haha.
A quick update on the ball getting stuck issue. I learned that the Coil - solenoid #A-26451, which is the coil that is used for ball release and outhole, does not always engage and release the lever that allows the next ball to pass through (it works around 90-95% of the time). Is it safe to say I need to replace this coil? I see it here: https://www.marcospecialties.com/pinball-parts/A-26451. If so, i'll buy it and replace it, then report back. Anyone not agree with this assumption?
Also get familiar with using Steve at pinball resource. He stocks a lot of gottlieb parts and is much cheaper than Marco. Only thing is he is old school and only takes checks and you have to set up an account. Also get a Manuel and right down every part number so when you call you will have it ready for him and not get yelled at haha. You will need to buy coil sleeves and maybe the springs for the pop bumper. Get extra and do them all at once.
