After looking at other engines I found this poulan chainsaw with a 40cc engine...however it says that the powerhead weighs in at 10.5 lbs !? Is that info right?

Its the "poulan wild thing 2375LE"

This one comes in at 11.8 lbs for 42cc "PPB4218 SAS"

Somehow I dont really think thats right...In anycase is there someplace you can buy the engine only for these things? Preferably used.
