I had 3 7900 that did the samething. They were in the shop several times each. When they run they rungood but i dont have time to babysit a saw so i got rid of them. I bough a 576 at a month ago and i like it a lot after i opened the exhaust up.I like how it starts in two pulls no matter how cold it is.
I bought a 575 when they first came out it was a dog and had quite bit trouble with it was one of reasons I tried the dolmar. Really like the 576 autotune smooth and good power.
