Disagree, they may not be as powerful as modern flippers but with a proper rebuild and good connectors, switches, etc, they should have ample power. I've played a couple Gorgars that had strong enough flippers to make them fast and challenging.

If anything, perhaps a video would help us determine what OP means by weak flippers.

Also, could you post some pics of the boards in the backbox, @Steveoshoots?

There's also good repair techs you can send your boards to if you don't feel you're ready to take on some of the work that may be involved. Chris Hibler here at pinside repairs boards. I've personally sent mine to the Coin Op Cauldron a few times, and there's many others as well. If you're gonna go that route, you may just want to send them all the boards at the same time and they can bulletproof and fix as needed so everything should be good to go when they're finished (as long as the rest of the game is ok). I personally prefer original boards over aftermarket, and these actually look to be in pretty nice shape. If you plan on keeping the game for a long time, it's worth investing in having these boards professionally fixed/bulletproofed. I love fixing my games, but i sent all the boards out for repair/bulletproofing on my first pin and 15+ years later they've given me very little trouble.

However, if you're up to the task, ThatOneDude's suggestion is right on the money: Vid's guides should have all the info you need to make it happen (or at least provide a good starting point). Plus there's tons of great techs here that are willing to help you along the way (as you see here in this thread )...

Good luck!
