so update on the Chusqvarna. still running the Chinese cylinder,and PTO side case. All else was swapped to OEM....(not sure about bearings or seals though) Bought another 372 that was from the original owner and it is 100% stock OEM down to the last screw, so I have something to compare the chusky to. Power wise the AM cylinder is a butt nugget compared to the OEM setup. Though, it has risen a surprising amount in the last couple of months. i guess it is finally breaking in props out to all who commented and lead me down this strange path.
I have since cut about 4 cords of hardwood, and about 5 of softwood, including a lot of noodleing....too many knots in the local wood, but it is free so FWIW I am not complaining. its about time to ditch the 42cc poulan and get me a quality smaller cc saw, have been talking on the forum about the 346xp so now I am looking for one of them need something lightweight for trimming and whatnot. My japanese bud just bought a little itty bitty Stihl it is like 25 or 30 cc but cuts like a raging beast for its size i wanna say it is a 180J ( means japan version) and it is kind of strange, it starts out slow and ramps up while cutting...definitely different form the way the husky's and the poulan works. almost like a 4 stroke. in its power curve. Damn quiet also hmmmm....
