Hi all.
So I picked up a very lightly used 550XP early Spring as a smaller alternative to my 359. Love the weight and power.
Initially it had a few hiccups where if I didnt mash the throttle, it would die. It would always fire right back up.
I attributed it to the AT learning. I tried a few things too that Id read here about resetting it, and that didnt work.
I had the local dealer look it over, and the only thing they could come up with after having it for a week, and tearing it down to do a bunch of other tests, was that maybe I had the wrong mix in it.
On their suggestion I ran only Huskys oil from there on.
It still had issues but not quite as bad, so I just lived with it.
The last two weeks though, Ive been using it extensively to clean up some storm damage, and its become a royal pain.
Restarting for every third cut is way past getting old.
The saw is excellent when its actually cutting, but its idle seems to have a few problems.
Maybe this is why the original owner was selling at such a good price...
A bit of info on my use, or how I run it. Im not sure its much different from anyone else, but could be, although I cant see how it would cause any issue with this saw, and not any others.
Before I start a cut, I bring up the RPM to about 50%, maybe a bit less. As soon as I touch the wood, full throttle.
Sounds stranger than it actually is in practice.
This initial light throttle application is what is causing the saw to die.
If I give it full throttle, it will sputter a bit, then go.
It really shouldnt sputter either, though, so I assume that too is part of the problem, or maybe whatever is causing that IS the problem.
I spent the last hour or so searching here for a solution, and it seems like most of the threads Ive found are at least a year old, and I didnt see anyone mention a known fix for this.
I have seen a few mention replacing the carb fixing some peoples issues.
Is there a known fix for this?
I am not a saw mechanic, and certainly not with the AT saws.
I am not sure my local dealer knows what they are doing with it, as they didnt even have the proper cord to check/update the AT initially.
I believe this time around I will send it off to someone who knows these things inside and out, like Spike.
Hate to have to do that, but I also really dont like paying someone twice for the same job, and feel like doing that would be a benefit in the long run.
