Oooer this sounds to me like you have the cart way too a**e heavy gb. Thing is , if you raise it too much you will highlight the 'highs' and your next post will be 'my cart is a paint stripper'. Are you absolutely sure that the bottom of the cart is running parallel ??. Forget the arm thats way to easy to be out with, especially if you wear vari-focals ?. Do yourself a favour. Pop over to the online auction site and buy a tonearm spirit bubble . They weigh next to nowt and dont cost all that much. Plop it on top of the headshell and away you go for a good start point, then you can tweak from then in. Need a foatie or link for your cart cos if the bottom is an odd shape then its better to look to see if the bottom of the headshell (top of cart) is level to the record.
