... have a SmartTractor and know there are YouTubes but feel ignorant and insecure. What do I need to do. When all properly set up will I notice a change?It’s impossible to say if you’ll notice a change with a more precise cartridge alignment because there’s no way to know whether your cartridge is setup satisfactorily now, or not. The SmartTractor is a good tool, and YouTube videos can be very helpful. As others here will probably tell you, it’s worth the time to learn how to do this yourself. It isn’t rocket science; it does require proper tools, skills (mostly dexterity) and patience.
