206 Rule UPDATE - Cylinder Head Gasket Surface is NOT a tech item.
Briggs & Stratton 206 Engine Rule Update – Non-impacting
19. Cylinder Head – (Updated 2/18/2019)
b. Cylinder head must be “as cast”. Factory machining marks on the head
gasket surface is NOT a tech item.
“As we continue to advance the machining of our cylinder head the need for a gasket
surface finish is no longer necessary”, stated David Klaus, Director – Briggs Racing. “We
made a promise to the sport 9 years ago about maintaining competitiveness right from
the box. We are proud to continue to tighten our tolerances and hone our efforts to a
precision that others won’t follow because they can’t or the cost to do so is too great.
Our combustion chamber tolerance was a fraction of the thickness of a hair and we have
reduced that fraction in half. While our previous tolerance would never be seen on a
dyno, now there isn’t even a discussion point.”
Racing is a passion that we do full-time. Providing stability through hand-built precision
that is back by a consistent rule set provides the cost-effectiveness that families deserve
and our sport needs. This IS Briggs & Stratton Racing.
