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.

I think this is a good (and necessary) move.
This addresses exactly what we were seeing/talking about at the tech seminars in Tennessee & Ohio.

Win-Win for Briggs, racers, and the tech guy.

This rule allows Briggs to use cylinder heads in inventory that have been cut using a second pass (rather than scrapping or recalling them.)
It also allows the racer to clean any residual head gasket material without concern of leaving a scratch and possible DQ.
It gives the tech man some solid ground to go by a measurement alone, rather than "appearance" and having to make an interpretive judgment call.

Right on the mark Brian. I really try to avoid any judgement / subjective calls.

Excellent update.
