Start by setting the pulleys so that both cables are equally tight
with the door lowered. You might have to clock the pulleys on the
shaft so that the clamp bolts aren't trying to settle into previous
"dents" on the shaft. Tighten the bolts on one pulley and rotate the
shaft until the cable is tight. Then clamp a visegrip on the shaft,
oriented so that it's jammed against the wall to prevent the shaft
from turning and unwinding the cable. Now tighten the bolts on the
other pulley so its cable is tight. Then wind up the spring and
tighten the clamp bolts. It tends to take about 7 turns of the clamp
anchor IIRC, but you'll have to experiment until you get it right.
Don't forget to lock the shaft with the visegrips each time you
readjust. And be extra careful, lots of people get hurt installing
garage doors. Make sure that the turning bars are a good fit and are
fully inserted before you crank on them. I keep a spare bar and a
spare wrench in my pocket in case I drop either.

Sounds like the cables aren't equally tight. Make sure that the door
isn't binding anywhere. The tracks should be oriented so that as the
door rises it comes away from the wall.

Once properly adjusted, the spring should hold the door in any
position, and the cables always stay tensioned. Take care that the
door operates cleanly and isn't so crooked or whatever that it's
trying to come off the tracks. You'll have a real mess on your hands
if one cable comes off when the door is partway up. And an even bigger
headache if it falls on your car or worse.

I think you'll find that once you've figured out the correct sequence,
it should only take about ten minutes.
