Just the dealer i bought the saw from.
I wish it had a different ID, but the cost of shipping it to the US and back is a little more then I want to spend.
I ran 2 tanks through it today and it worked fine.
Before the 3rd tank I removed the spark arrestor. I also went from an 18" bar to a 16" bar. The last 3 tanks it seemed to perform a fair bit better.
I know the shorter bar would help but am wondering if losing the screen would make a noticeable difference?
