You know Gregg, you brought up a really good point. I have a 4200, a 4900 and an 8500 and have used them quite a bit of late. I know I am getting old and as my boys tell me, senile, but for the life of me I cannot tell a great deal of difference between the three. The 4200, at only 69cc is a real sleeper.

Like the Dolmar 6400 and 7900, the Poulan's in this series have different size bores, but the same long stroke. That's what gives you torque.
And these saws sure are purdy.
