RE: Need Help Tuning An O.S. Engine
Wayne,
While you are at it, please do the break-in according to [link=http://www.rcuniverse.com/forum/Tapered%2DBore_Engine_Break%2Din_%2D_Upgraded/m_1850473/tm.htm]this RCU thread[/link].
The OS manual is not detailed enough, to help you understand what you are doing.
Tuning the idle/mid-range will just be futile, before break-in is completed.
