I picked up a 066 Magnum and 038 Super at a junk store this weekend and cleaned them up and they both run great. I tested them each with a 24" bar and chain.
The 066 muffler had all the internal baffle chambers removed. Does that mean it's Walkerized or Madsenised or just a field modification (ie headers)? It took out a 20" stump in mere seconds. The sound of that saw at full throttle sounds is awesome. Does the 066 hold up OK in durability.
The 038 Super seems to weigh nearly as much as the 066 Magnum, but didn't have the power of the 066. It sure runs nice but it's a tad on the heavy side. Would it stand a chance up against an 372XP or 044 in capability or reliability? I think it should marry up nicely to about a 20" bar. What CC would you guess a 038 Super to be??
