just been reading for a while about new husky saws, just bought the 74.5 cc 372 was wondering if the carb has a cat, and if so should i change it out. if i should change it out what is the part number for the non cat muffler, thank you all...i bought the saw for bigger wood cuting, i put wp rc chain with 24" pm bar on it. would i be better off with skip chain for this setup? i havent used the saw yet. im used to using my 290 farm boss and husky 350. p.s. i have an old homelite c72 that i want to sell. its all there, havent started it in 2 years though might need a carb kit.
