Last month we introduced you to the Briggs Racing Local Option 206 engine platform. This month we want to expand on this topic. As we told you last month, the LO206 is an Animal engine with a few minor changes. The ignition module limits the engine’s rpms to 6100, and the crankcase is double sealed from the factory. Piston popup is also very tightly monitored to provide consistent horsepower and keep the competition between the drivers and the karts, and out of the engine’s hands. …

With the recent release of the Junior 206 crate engine a new approach to horsepower restriction comes on the market. The Walbro extended slide (555728) and locking cap system (555726) provide the ability for almost unlimited horsepower control without the negative effects. If you have a class you want to mix or match or are looking at a new racing application at a certain horsepower, this is a foolproof, cost-effective, easy to tech option.The concept and execution are simple. If you …

Sometimes, it’s just a bad day. You get to the track, everything is ready to go, roll up to the grid, pull the rope, and it just won’t start. What do you do? Where do you look first? These are just a few of the questions that we will answer in this month’s installment of Grass Roots Tech Barn.
An engine needs three things in order to start; fire, fuel, and compression. Let’s address the fire first. The ignition system on a Briggs is pretty simple and has only three components. The coil, the …

The spark inside your race engine is pretty simple, high voltage is used to jump a gap and create the heat needed to get combustion started. The spark itself is pretty simple, but getting everything to happen just right isn’t that easy. Spark timing is one of the most critical tuning agents we have to maximize power. If it isn’t right within a degree or two, power can be down. With the stiff competition of today’s racing, a loss of power because of bad tuning is unacceptable. We work too …

Over the last couple of months, we have been building our toolboxes for the track and the tech barn. Although many of the tools are very general and self-explanatory, there are a few that require further explanation on their application and use. This month, we will dig into and explain a few of these specialty tools.
The flywheel tools can be a bit overwhelming if you have never used them before, but in reality, once explained, they are very simple to use. The tools necessary vary whether …
