Check the listing for details. Hudy Engine Break-In Bench [HUD104140]. Condition: New. Listed at 182.99 USD. The HUDY Engine Break-In Bench is the ultimate tool for easy, safe, and professional break-in of .12, .15 and .21 size SG crank bump-start engines. The bench allows for a controlled break-in process that reduces wear & tear on engine components and increases performance, reliability, and longevity. Constructed of top-quality aluminum and spring steel components, the Break-In Bench comes partially assembled from the factory to get you running sooner. A thick aluminum base plate with integrated clamps allows quick, solid mounting on any workbench. A large protective propeller shroud safely covers the included prop. Includes pre assembled throttle linkage, universal engine mounts, large-capacity 125cc fuel tank, prop spinner, and all necessary hardware. Requires use of an electric drill (not included) to spin the prop to start the engine. On-road type header is required to route the exhaust the correct direction. NOTE: May not fit RTR engines or rotary style carburetors. Customers may need to make modifications to work in these applications. HUDY/AMain Hobbies assumes no responsibility for any damage or injury caused by any modifications to the Engine Break-In Bench or engines. The break-in bench has been designed for .21 engines. However, most .28 motors currently available are a larger bore/stoke version of a standard .21 and should fit on the bench. About Us | View Store
