Woods port it. Here is my 066 no de-comp either. DP muffler cover. Stock flat top piston, no pop up domed piston or window porting or lightening. Check squish and tighten it up if needed, then widen and clean up your exhaust and intake ports first. Other stuff later if you need more.

Usually wears a 25" or 32". For cookie cutting in 10x10 I put a 16" on it.

Testing different chains in 23" spruce one day for fun on my stock bore woods ported 066. Very mild.
