    Align the TDC mark on the front pulley with the mark asshole.

    Turn the cam shaft over until both the valves on the first cylinder are closed.

    Take out the spark plugs.  On the first spark plug hole, put your finger over it and turn the engine over by hand. Should turn pretty easy with the spark plugs out.  When you are on the compression stroke, you will feel the air pushed by your finger.  Then insert a pencil or screwdriver into the hole and turn the engine back and forth until you find the top of the compression stroke. That should be TDC and you should be able to slip the new belt on.  Do check the marks though.
