Removing a Weed Eater Engine and Running on a Stand - 4 Stroke

Makita Impact Driver Used: amzn.to/2vUrcKc
In this video, we are pulling the engine from a Ryobi S430 30cc four stroke string trimmer/weed whacker. This engine has a steel overhead cam and is functionally very similar to a car engine except that it is a whole lot smaller. To tear everything apart quickly on the weed whacker, I am using a Makita SDT131 18V LXT Lithium Ion cordless impact driver. Once the engine was removed from the trimmer, I mounted it with custom engine mounts to a 2 x 6 piece of lumber and started the engine up. To show how the valvetrain works, I removed the valve cover while the engine was running. This is a DIY project that is pretty simples and will demonstrate how a four stroke engine works.
