I am really hoping that the money that Briggs has invested into short life tooling, and exceptional factory assembly will kill any real advantage to high order tuning. At the higher levels of competition, creative intelligence will always dig for those 1/100 second at a time incremental gains. However, within the specifications that are stated for the engine, an out of the box engine with a basic valve and float adjustment should be close right? Chassis, tire management, physical fitness etc. should trump any possible "Legal" tweaks. Attracting and retaining quality people and better yet families to this sport is vitally important these days. This class has gained a lot of interest by what I would call the elite level racers. Advanced tuning always follows shorty behind. And that's where the fight generally starts. My personal tuning flow chart for the LO 206 is as follows: 1. Basic maintenance. 2. Pull rope, does it idle? 3. Does it pull clean from corner to corner? 4. Does it hit limiter? 5. Stop thinking about it and learn to drive smooth with as little braking as my ball-nutties can handle. I hope that this package survives where virtually every other controlled class I have either raced or championed in the last 20 years has not.. We need it.
