Using this Briggs LO206 engine is quite straightforward. First, make sure all the components in the kit are properly installed, like connecting the fuel pump line and the pulse line. If you've chosen the exhaust pipe kit, install it following the included instructions. When it comes to using it in junior classes, always double - check the slide color rules with your local track.
