Hello!  We have an excellent Briggs 12H802 1986 B1 engine from a Karcher pressure washer that has been cleaned, carb removed and cleaned, OEM needle and seat kit, new head gasket, spark plug and air filter.  Engine was test run for 30 minutes without issue.  This model has a manual choke.  Please note the attachment shaft, as it is configured for pressure washer use.  The shaft length is 3/4" and the hex bolt is 7/16 x 20 thread.  Engine shipped without oil due to shipping regulations and via FedEx unless otherwise requested.  Model of washer is unknown due to sticker worn and unreadable.  Please feel free to ask any questions you may have and visit our store for complete small engines, small engine parts, antiques, collectibles, farm items, sewing notions, holiday items and so much more!  Thank you for viewing.
