Briggs & Stratton Junior 206 Crate Engines

Briggs & Stratton Junior 206 crate engines are made tough! Each engine is hand-assembled in-house using tooling and dies specifically made for racing--for unparalleled repeatability. The factory-sealed long blocks include a ground cam and controlled piston pop-up (reducing compression variance). They're a simplified IKF/WKA rule set designed to maintain a stock configuration, right down to the factory carburetor jets. These 206 race engines are powerhouses!
