When you pull in the clutch handle all the way does it still Die?
If so try screwing in the Idol screw Until it revs UP a little then back out until your happy.

Grinding? Check the clutch cover, inside for ''grinding" marks.
Not very fast is a symptom of a new engine, break it in for a few hundred and it will slowly get faster.
