    When I installed the chain I tried to move my bike and it would skid. I am very confused on how to install the clutch. Even when I pressed it and let go I still couldn't move my bike. Could it be the cable was to too tight

    on the contrary, the clutch cable may be too loose.
    when you squeeze the clutch lever, it should pull the cable, which in turn pulls the clutch arm on the left side of the engine. the clutch arm needs to be pulled far enough to disengauge the clutch.
    this is a hard thing to understand if you don't "get it" or know how a clutch is supposed to work.
    The arm should pull far enough to disengauge the clutch.
    when you squeeze the clutch lever, your bike should roll, and when you let the clutch lever out, the rear wheel should drag or skid (with you off of the bike).
    with the clutch lever out, you should be able to wiggle the clutch arm on the left side of the engine with your fingers. It shoudl just wiggle back & forth and there shouldn't be any tension on the arm.
    with the clutch lever squeezed in, the arm should rotate in towards the right side of the bike, and it should be stiff, with pressure on it. you should not be able to wiggle the clutch arm with your fingers.

    On the other hand, if you have the cable adjusted right, there have been cases where a clutch has gotten stuck internally. This can be caused by the engine sitting for a long time proir to it being sold. sometimes ther can sit long enough for rust to build up inside the clutch and cause it to stick.
    I've never had that happen so i'm not sure how to fix it (if it is that) but i'm pretty sure that you have to take the clutch apart to get it freed up if it's stuck.

    very first thing to do is take out the spark plug and roll the bike

    this will tell you if the engine is stuck or the chain is stuck if the engine doesn't move without the plug in it

    Should the bike roll when the clutch is pulled to the left. It just wiggles

    if you're talking about the clutch arm on the left side of the engine.
    NO the bike should not roll when you pull that arm to the left. That's the opposite way that it is supposed to be pulled.
    with the clutch lever released (on the handle bars) the clutch arm on the left side of the engine should move to the left.
    with the clutch lever squeezed in (on tyhe handle bars) the clutch arm on the left side of the engine should move to the right.
    with the clutch lever released (on the handle bars) the clutch arm should wiggle. with the clutch lever squeezed (on the handle bars) the clutch arm on the left side of the engine should not wiggle and it should have tension on it.

    exactly.

    looking from above, shaft rotates anti clockwise to DISENGAGE clutch. remove the OPPOSITE cover (five screws).

    you will se a large gear with an ugly little nut and screw in the centre, a big shiny steel disc too.

    when you rotate the clutch lever anti clockwise the steel disc should move a few milli metres away from the gear.

    at this point you should be able to figure the rest out?

    engine drives gear... gear drives friction pads. strong spring pulls disc onto friction pads. friction pads drive disc. disc drives sprocket and chain.

    lever on motor pushes, via short bar, on the back of disc. disc lifts off friction pads.

    ugly little nut in centre of disc governs how far disc moves off pads. or how hard it pulls on. lil screw next to nut stops nut from turning.

    every new motor ive had has needed a good kick to free the clutch up at first.

    So the cable on the clutch lever has to be tight.
