which mark to align cam sprocket,the last mark,is TDC,please help

You've just answered your own question.

The last mark is TDC. The T stands for Top.
Turn the crank anti-clockwise (viewed from the left of the bike), so that this last mark is aligned and then fit the cam sprocket on the correct marks, keeping the chain tight at the front, with any slack to the back - the tensioner will take up this slack.
Job done - time for a beer!

the rotor has not got the letter T on it,i set it to the last mark seems ok started 5/6 kicks what are other marks for???
new problem the carbs kiehen CR specials,can adjust one mixture screew,the other mixture screew makes no diference in or out,yes i have cleaned them,still it gos like shit off a shovel,the bikes a hooligan
