Graham Phantom: Set Up Error Causes Skipping

I just installed a Graham Phantom on an Aries. I have some Wally Tools and a Fozgometer, but this is the first time of done this and I'm sure its far from dialed in. I have some LPs that I know are in reasonable shape and played fine on my Scout / JMW 9. However, these records skip. Where am I going wrong? Is it anti-skating? I have tried to set it on minimum. Any responses would be much appreciated. I am a novice. Thanks!
