Sprayed with WD 40. Worked a treat they go down but they don't go back up straight away for some reason. Two of the three register on the score board.
Strange thing is the coil works as they come up when it's trying to detect a ball.
(It's the ones on the side, weasel drop targets)
WD 40 may be a temporary fix, but is generally frowned upon as far as pinball maintainence is concerned.
Having said that, a squirt or two in your car gearbox may not be entirely out of place.
