So I just picked this up. Starts fine but stalled out a couple times and once laying flat in a face cut. Sometimes takes a few pull start after shutting it off for a few minutes.
Previous owner said it has a new ring and was tuned?
How long does it take for a ring to seat?
I tried a reset, running it full throttle will scribing down a 30’ or so beech tree.

Nice saw. I hope you get the issues ironed out.

and was tuned?

I'm the guy that would have totally asked how it was "tuned".

Thats what i was thinking too

 

[farminkarman]

It probably has an air leak. A saw that looks that nice should not have needed a new ring.

 

[woodfarmer]

So he told me to turn the idle up.
The piston doesn’t look too bad does it?

 

[Woodpecker]

That’s a lot of carbon build up in the exhaust. That piston, while probably still functional, doesn’t look great. I’m with Greg, pressure/vac test it for an air leak and go from there.

Yes, indeed. I would add to check the ring for collapse either physically by pushing on it with a popsicle stick through the exhaust port to see if it still springs in and out or check the secondary compression. At any rate, it should still come apart to clean the carbon out of the port and the failing should present itself then. Cylinder should be checked over very carefully and sketchy looking piston for possible replacement.

It's not that nice, has a Husqvarna brand front handle on it. Which is kinda of a clue as to where this thing could be going.

 

[huskihl]

Looks carbon scored to me. If he replaced the piston, he didn’t clean up or fix what caused it to go bad the first time. Run better oil

 

[Coupe]

I am with the others on this one. Lot of things that could be causing it to do that
even a fuel problem and if you have one of those spark testers put that in the ignition
line and make sure it is not losing it's spark for a split second.
Think the first thing I would do is a compression test by looking at the piston and ring
and see what you come up with from there. If that turns out okay I would do the carby and yes
test for an air leak but if it is I would pick it would keep doing it all the time.
It is a case of eliminating things one by one what you yourself mite think it to be.

 

[Coupe]

That is the other thing which could be the tuning. Whats it running like
after it has warmed up a bit.(Is it still stopping) If you know how to
tune the carby give that ago and I know the rule of thumb is to
tune when they have warmed up but think I would try it cold to see if
it is not to lean or rich when cold.

 

[woodfarmer]

Ya, auto tune!
So I bought it on EBay the seller claims he pulled the muffler and it looked fine before he shipped it to me. I doubt that.
He won’t say who or why it has a new ring.
Then he says I’m being disrespectful and difficult?

 

[cuinrearview]

The clutch cover looks like Chy-na. Nothing in his description is technically a lie, but I'd return it with the piston looking like that for the price you paid. JMHO

 

[woodfarmer]

No returns, he’s sending me a good used piston and cylinder. We’ll see.

 

[cuinrearview]

No returns

Must be a Canada thing. The buyer is always right down here.

 

[woodfarmer]

Yep. He said the piston looked fine when he pulled the muffler before he sold it.
I ran it for 5 minutes and could tell something wasn’t right.
He said he has no control after a saw leaves him and it depends on how the fuel was mixed and how it’s ran.

I don’t think so, I run the same fuel in my 500i’s and all my ported saws.

 

[woodfarmer]

So looking thru the exhaust hole, I can see it looks like someone has rubbed the cylinder with a scotch brite pad. I didn’t have a small light tot look thru the plug hole to see the exhaust side

 

[woodfarmer]

It’s headed back today!

 

[hacskaroly]

It’s headed back today!

Glad to hear he is taking back the can-o-worms, sounded like he was trying to pawn it of on someone who might not know much about saws and just accept it.
