Review: Generator would shut off after a couple seconds - Bought a used champion generator, would shut off after a couple seconds, I clean the carburetor, new fuel and same. Replace the avr and brushes. Starts and runs like a champ. Champion generator 4250
Review: Now my generator is like new - I was dealing with a problem with my generator and the best solution was to replace the brushes and voltage regulator in the same time. Here the set come together and now my generator is running like new. I live off-grid and when the snow cover my panels after few days, I need to rely on a generator to charge the batteries. I will buy another set to have a spare one. I will update my review on reliability, if it won’t last.
