Sorry if this may sound a bit discouraging, but are you absolutely sure that
you followed the book by the letter. Because if you did, you wouldn?t have run
into this problem. I still suspect your timing is a bit off. Not so much that
the pistons collide with the valves, but enough to loose some performance. I
would take it apart and check it.
