The compresion on shocks I understand but ajusting of the rebound I do not get. I cant imagin any time that I would not want a shock to rebound as quickly as it could so it could be ready to compress again. What is it I am missing.

Speaking in theory if you had your shock's rebound as fast as the setting would allow it could create a bouncy ride. When the suspension was compressed hard it could kick back too fast taking weight off the track making it loose.
But I agree with you, short of it feeling like a pogo stick I'd want that shock ready for the next bump asap.

x2 like he said you will get to much kick back if set to high because it let's the shock pop back out to fast for your riding style Also let's say up on your front shock's you backed off to far on your rebound your sled would start to nose dive because its not rebounding fast enough. You just have to play with it on the trail and you will find your sweet spot. Thers's no set setting for everyone, it all depend's on how you ride. Just make 1 adjustment at a time, ride it, feel what it did and go from there. if it feels right make a note of it and maybe adjust more just to see the difference. you can always go back.

Good question…re-bound is very important. Let’s say you have it set up to full compression (hit the bottom) at your maximum capability. (speed, weight and height) When you have reached that point..full compression…the suspension has done that part of the job (speed and weight) and then wants to get back to it static position.
Think of the force it took to get it to full compression..well..when …at that point the skid has virtually no compression forces at work..so..it will snap back pretty well pitching you over the bars.
Best place to see this action is at a pro race..you can actually see the skid coming out of compression as they leave the lip of a jump after a compression valley.
The good news..there is no end to getting it right..it is never right…always room for improvement.
Also..the sled I’m driving at the left..the front shocks were the key to making that thing handle in its day..compression rebound were extreme important…

Well thats a hard one to ansewer every body likes it set diff. but the adjuster on the shock doesn't do that much like a revavle would do its more for fine tuning the shock u can slow it down alittle or speed it up alittle its all in how u ride . But one thing is u want the front & rear to be bal. together meaning u don't what the front stiffer than hell & the back soft or the other way around . Anyways there is no one setting that is perfect just play with it . GOOD LUCK

Well for snow wheelies i would suggust soft rear and hard front !

Compression and rebound control the rate that a spring will to accept or release energy. When the Compression is set "high" the rate at which spring can respond to compressive forces is reduced (damped), which will be felt as a harsh/stiff ride. The opposite is true when the compression is set too low.
Rebound affects the rate that the spring can return to its neutral state. When the rebound setting is too "high" the spring is overly slowed on its return to the pre-compressed length. In the extreme the spring will pack down over successive impacts because it can’t extend fast enough between hits. This reduces effective travel and compliance. When rebound is set too low the spring will unload rapidly and tend to kick the shock or ski downward and you, over the bars.
Shocks control the springs, not the other way around.
In air shocks the rate of gas flow between chambers controls the compression and rebound response. The gas, because it is compressible, provides the "spring" force.
