ok i picked up my two new saws today from my dealer=husky 395xp, and husky372xp, he said to run a gallon of gas thru it then bring it back to the shop so they can fine tune everything for both saws, does this sound right? and what is the correct breaking in process if any? (can you tell these are my first new saws )i started the 395 up and ohhhhh boy! music to my ears same with the 372,kinda gave me the chills lol alot diff than the 32yr old stihl 045 ive been using, thanks guys
