Typically, the more your level bubble is off, the worse the issues with the motors. For non-motor mounts, you should be able to tweak and make it ok. Shucks, when I was originally starting out and didn't have a motor at all, I just wired a little 18" dish to a pole on my porch with some cheap copper wire and it just sort of hung there kinda almost blowing in the wind. Basically, tweak as well as you can, and once you nail the signal, figure out a way to make the dish stay put there as well as you can. In the end all that really matters is that the lnb is aimed the right way. If you are going with a motor, you may try leveling the bubble just a smide more, maybe with some support wires attached to the ground (or roof if this is a roof mount)... I had to add a few support wires on my setup - just a couple extra little wires to help stabilize the dish and bring it level more prefectly. I used to have the same leveling problem you seem to be talking about before that.
