Quoted from yuriijos:
So if you read the manual it says to install the playfield bubble between the marks, but when I do that and use my tilt meter it is not at the recommended 6.5 degrees? What do you guys do, set the incline between the marks or use your own?
I use my cell phone. Download the Clinometer app. 6.5 degree between the flippers and zero left to right further up on the playfield.
