Hi all have a lah over at my dads house ,with the holiday party's about to start up would like to fix a annoying problem.ball will not launch in to the shooter lane or get to and from the vuk,happens intermittently ,if ball gets up to shooter lane coil will just pulse lightly three times .I have also noticed that we dont have to pull the trigger to launch ball ,can just hold down left flipper button to launch is this normal?looking for ideas to check out . Thanks Happy Holidays pinheads!!!!
