Rember it had spark, so don't think plug would be the cause. And I
replaced the gas with fresh.

Per the dealer -- there is cyclinder damage. They are talking to the
Dolmar rep today. I have yet to call.

This is clearly a design or component defect as the saw was bought new
in June of 2009 and used through 1 gallon of gas. The dealer noted
another saw had been brought in recently with the same issue.

I'm going to call them today.. and insist on :

1) root cause of failure
2) new saw or full refund

I simply cannot accept paying full price for a new saw that with a few
hours on it would be subjected to a major overhaul.
