This is a short introduction to the LO206 Briggs & Stratton racing engine explaining cam timing and how the rules are so loose the builders are cheating it. LO206 is a box stock engine with a rule set that is for karting. the Concept is simple buy you car, take the engine out of the box and start racing. The engines are to be equal but this could not be farther from the truth. After the engine builder funny business they are drastically faster. The biggest cheat is the hardest to preform and the hardest to catch because you cant see it or hear it but you are now faster than the rest of the pack. The cam shaft is being twisted to a more favorable position and the current 2023 rules allow for it. The first cam number at .006 you are allowed 8 degrees of variance and other numbers 48 degrees also so bend the cam in the neg side not advanced and you will have a rocket. They have bee doing it since the flat head days and it is still going on today. Briggs could stop it all by fixing the rules but the national kids would have a much harder time wining. This advantage is preformed by certain builders for certain kids for the parents of influence. There is a simple fix to the problem and Briggs wont do it. First you could tighten the rules to be 1/2 degree of the stock cam and then they would have to release the cam center lines. With a center line in place the twist game would be over. Briggs claims to take 3600 points on each cam to ensure they are all the same so the problem is not with the manufactured parts but with the amount of room in the rules for the twist. with 48 degrees on the table you only need 4 degrees to get max performance of the engine so the rule is wide open. since many don't understand what the numbers mean they don't know what they are looking at and it is slipped right into the rule book. Briggs knows all about the problem because i have been asking them to fix it for years. So just know that when you get into this form of racing the engine will not be equal and catching the front of the pack will be a bigger task than you think. Many have been calling for this to be fixed but Briggs is no longer commenting on the problem. Briggs on 1152023 did release a new rule stating that they have all the engine numbers and know the cams that came in each engine and are going to release them to "tech Officials" but no tech official i spoke with has them or can get them. the rules need to change or the tools will be developed so everyone can have the same advantage.
