I recently picked up a stargate for the first time. It came with the typical set of problems - bad RAM chip, blown 4-opto boards (missing the big resistors) and of course the burnt out rope light.

I've worked through all the bugs, but have one very annoying behavior I can't seem to figure out. In Glidercraft mode, the scissors pokes the glider craft all the way out twice and then the glider reaches about an inch out of parked position and swings back and forth continuously with pyramid up until the end of the mode. At that time, the glider craft jumps all the way out and parks correctly stowed and the pyramid drops.

My question is what can I do to make it fully extend throughout the mode? Is there some way the game knows when it is extended? Do you think the wrong motor might cause this?

The game has been routed, but it is still quite nice and it's now scoring perfectly, but the arguably best toy in pinball is being a little shy.

Thanks for any ideas or tips.
