2019 Briggs & Stratton 206 United States Rule Set Released

It is hard to believe that the Briggs & Stratton 206 program is starting its 10th year of competition.  That is 10 YEARS without a rule change that has impacted any 206 engine or short block that have been built.

“How many other engine platforms or rule sets can say that?” stated David Klaus, Director – Briggs & Stratton Racing. “Imagine the financial impact that engine or rule changes have within our sport.  One of the building blocks when we started this program was to keep racing affordable through stability.  We are proud of this accomplishment and would like to thank our racers who support us in this continued quest.”

A second building block to this program is consistency through manufacturing, machining, and final hand assembly that gives racers the ability to open a box and be competitive on day one. “For 9 years we have seen engines from the box reach the podium at the highest levels of racing.  This consistency is fundamental to ultimately controlling cost.”

The 2019 rule set maintains these building blocks while reinforcing our continual commitment to tighten, not relax tolerances without impacting what we have previously manufactured.

The top line updates are a reduction in piston pop-up from .005” to .0035”, a change to our combustion chamber depth measurements and overall cylinder head thickness.

“Let me stress that these updates will have ZERO impact on any engine, short block, or cylinder head that we have ever built for this program.  The only possible way a racer would be impacted is if they took it upon themselves to make illegal modifications.  If there is any response to the narrowing of a tolerance then let their integrity be known.  It is as simple as that.”

In addition our Go and No-Go standards will be defined by classification and size of each pin gauge.  By exact specifications we can eliminate any possible tech variance when it comes to gauging.  “I might sound like a broken record but this again has ZERO impact on any part we have previously sold.  It is simply an assurance that every tech official is on the same page.”

Lastly, As we move forward with this program we will hit a point where we will see a small transition.  Engines built up until 2013 identified by not having a colored seal wire (verses a single black or black and red) will no longer be eligible for competition in 2020.  We expect this to have very little impact given the age of these products today as well as the advanced notice given.  As with past rule sets any update year over year is highlighted in RED.
