also my cns is a pain to tune. me not knowing what im doin and all
Most folks up the size to 1/4". I don't think that there is enough metal to go up to 5/16 or larger. The wall thickness of the mounts gets to too thin at those sizes. Look up Al.Fisherman for alternative mounting tricks.

Also there is an excellent thread on tuning the CNS:
"It's a chinagirl. It's a sometimes fun little engine that often will break your heart. It's disposable.
