I have been reading and seeing that most everybody that has a 420 likes them. I decide I wanted one and I got myself one. I changed out the muffler for a noncat, I could have neutered the cat, but I didn't want to mess with it and wanted to see the regular muffler anyway. There are no baffles in it at all. I also swapped the 3/8LP b&c and clutch drum for a .325-7 clutch drum from a 5105 and a 15" oregon pro-lite. I have only started it once so far, she seems pretty snappy. Can't wait to try it out. I included pics of the new muffler. I weighed it, out of the box 10.88 Lbs, new muffler and .325 drum 10.58, b&c full of fluids 14.05. It is a little heavy for 42cc, but I don't care.
