Most of that comes from a rat-a-tat-tat from the pull starter area. Your right! My Champion C46540 is now quiet! This is what I found. The cooling fan on these engines are not cast with the flywheel as found on older engines but is a separate piece of plastic held only by the flywheel/starter cup nut. This apparently causes some vibration/oscillation with the fan while running. Some may be worse than others as mine was very loud. The cure? I removed the start recoil (10mm x 3) than the housing (10mm x 4). Next the flywheel nut (19mm x 1). The plastic flywheel will fall off, I cleaned the flywheel surface and backside of the fan to remove any grease or oil than ran a bead of silicone around the center hole and around the outside of the flywheel leaving a gap for the ignition magnet. Put the whole thing back together and let it set for 24 hours. (well, 19 hours - I couldn't wait to hear the results!). QUIET! Not that much louder than my Honda 1000 inverter unit! And to think I almost sold it at work last night! Now for the test. Will it hold together? I think so. Did I void the warranty? At this point I don't care. I'm just so happy it is as quiet as everyone elses! Happy boondocking! Another vote for this simple modification. Did it a few days ago and noticibly quieter. I noticed some bare metal were the fan had obviously been vibrating against. The key is to add a pliable seal under the outside lip and the inside lip to keep it from smaking. Kind of like a spacer. Took about 20 minutes to do.227Views0likes0Comments
