You did good. Sounds like your telling him the parts would come out if no under warranty got the ball rolling there, good for you. That was very odd the way I see it. He's waiting on warranty approval after he's already done the saw, doesn't make sense to me. If they said no and you said you wasn't paying either what was he planning on doing, keeping the saw untill someone pays. I'm glad you got it striaghtened out and all turned out well.
Yeah, I wondered about that myself. On the other hand, maybe I should just chalk it up to this dealer's lack of experience with chainsaws, or maybe with this distributor. I don't think he has been selling saws long, and his main line of business seems to be yard maintenance equipment and snow throwers. He appears to be learning fast though. Yesterday I took a look to see how he had set the adjustment screws, and this is what I found:
It looks like he removed the limiter tabs. I turned the screws 360° before putting them back where I found them.
RPM maxes out at 14430, unloaded, and the plug looks dark chocolate, or maybe black-strap molasses, brown.
The comment made in this thread that cold weather can drive a high-strung saw like this over the edge in combination with E10 and the lack of a slightly rich setting may well be right on the button. My saw failed on 0°F day.
