I recently got the Senac LLC Replacement Run/Choke Knob Switch for my Predator 3500w inverter generator. I needed a new knob because the old one broke. I found this one online and decided to give it a try. It’s a simple black knob. It’s made for Harbor Freight Predator 3500w generators. I installed it myself. The installation was pretty easy. I just had to remove the old knob and put this one in its place. It fits well. It feels sturdy. I tested it by starting my generator. It worked fine. The choke and run functions worked as they should. I think this is a good replacement part. Senac: Predator 3500 knob. I use my generator for various things, like powering tools in my workshops. I also use it when I go camping. I’ve seen similar knobs on other machines. I’ve even seen them on some small engine chainsaws, but they don’t always fit. This one, however, was designed specifically for my generator. I don’t see any blink or swivel in this knob, it’s just a simple, functional part.
This replacement knob is a practical solution. It gets the job done. I don’t do much arts and crafts, but I know some people use generators for those kinds of things too. I needed a reliable part.
