I was playing Black Hole tonight and noticed a couple issues. The game is pretty bulletproof at this point between doing the ground mods, new connectors, and even a couple new boards.

Here are the oddities I noticed:

1. Ball hits the glass right off of the flipper. Do Gottlieb flippers need a certain type/size of rubber? Or, is my machine too steep?

2. Really fast shots to the cellar don't register. I can predict which shots won't register...it's only the ones that are fast clean shots. Is there a way to mod that switch to register those short contacts, or is this just a manual adjustment? Slower shots have no problem at all. When it doesn't register, it's an instant drain on the bottom playfield.

3. On the main playfield, the capture ball hole always takes two attempts to kick it out. Not sure why.

That's about it. Only #2 affects gameplay....and it's really frustrating when it does.

1. Not sure, maybe your flipper is a little misoriented. (angle to the glass)
2. Adjust the switch better or put a capacitor to slower the signal to cpu
3. Check if the mechanism is moving freely, change the sleeve, the spring etc ...

Gottlieb flippers take a narrower rubber. If you look at the flipper there's a little groove that the rubber sits in. If you use a standard flipper rubber on there it doesn't sit flush. That being said, even with the correct rubbers I've found that there are still a higher than average "smack the glass" shots in Black Hole.

I have a High Speed that wouldn't see very fast shots on the ramp, I cleaned and adjusted contacts forever. Nothing helped. Then I just put new gold switches in and no more problems. I think 30 years of cleaning had worn all the gold off. Also try raising your flipper bats a little bit. If they are to low its like a pop fly in baseball.

Thanks for the replies.
I'll try cleaning the switch, though I have done that a few times already. If it doesn't help, I'll put in a new one. Out of curiosity, what kind of capacitor would I put across that switch to make the signal slower?

I'll try some narrower flipper rubber and see if that helps. That glass smack sound is awful!
