Hi Denis.
Here's something that you might want to post as a reference:
http://books.google.ca/books?id=p3ZHkkm4QU0C&pg=PA130&lpg=PA130&dq=effects+of+timing+vs+heat+dissipation+two+stroke+engine&source=web&ots=J60u0YcDwA&sig=HGcp2X3WZc0ORa1PWQE4jhATs5c&hl=en&sa=X&oi=book_result&resnum=8&ct=result#PPP1,M1
Cut and past the above link into the address field, then hit "Go".
It's a big document and takes time to upload. Very much worth the wait. If it seems to be taking too long, hit "view" drop down menu then "refresh"
