Briggs & Stratton 8 hp 4-stroke motor, pull start, side pole, shaft 1", stepped up to 2" (see pic). This motor was used on a special effects rig 5 years ago, and has been sitting in storage ever since. It's stamped as a commercial motor, so it's made to run. We paid over $1000 for it new. Install this baby on a go cart or minibike for some inexpensive fun! This motor only has 5 hrs on it. It is sold "as is" and "where is" (Simi Valley, right by the 118 freeway).
