2 Husqvarna Saws, same problem

[kwbobwi]

A friend of mine dropped of to Husqvarna's that had the wrong gas run in them.
The 460 Rancher X Torq is apart and the 440 X Torq is still locked up.
Looking for suggestions to rebuild them including the best place for parts.
Also need to know if during rebuilds is a new crank assembly with connecting rod is typically done at the same time.
Yes I've rebuilt small

engines before but not 2 strokes.

Watch out... You may get "Hooked" on building and modding them. I sure have.

Those saws look basically new were they straight gassed out of the gate?

I have been buying parts from Wolf Creek Saw Shop, and also more recently a new saw from HockFire Saws.

Best I know they are low hour saws.
As far as modding goes that's a possibility if I can get these 2 up and running for less money than replacing them considering they aren't much of a parts money maker

You might get lucky and possibly being low hour just stuck the pistons due to heat and no lube. Or not.
Get the top cover off and remove the muffler then take a look into the exhaust port and depending on where it seized the skirt and rings should give a clue on how bad the situation is. The plating on the aluminum cylinder can be pretty tough and maybe survived -the aluminum pistons are much softer and can get scuffed up bad and then stick.
If a ring hung up or a circlip came out of the piston pin area, things can get ugly quick.

Hoping for minimal damage.
Hyway, Caber, and OEM are all available as well as dirt cheap no name cylinder/piston kits as well.

As much as I hate to admit it, I bought a piston kit from Scamazon for $15 and it worked great. SIL had bought a Husky 254 that wouldn't start, long story short the piston land was busted. He bought a piston kit from a dealer for $50 and the rod wouldn't fit between the two bosses. He took it back to the dealer and was told , " That's the way they come, you have to file the sides of the bosses to fit".
I went looking for a piston kit and a member here pointed me to a well known aftermarket brand and it was over $70 plus shipping, not gonna happen, so I figured nothing to lose I bought a Chinesium one for $15. It arrived, fit like a glove, saw's been running great and he's got a couple dozen hours on it so far with great results.
I like to buy local too but there comes a time when someone tries to tell you something that isn't so.

That’s great!

I am trying to envision my “retirement” in the decades ahead. I am thinking about a chainsaw repair shop and fixing old muscle saws, but that’s just a fantasy for now.

Thats cool you finally got something to work.

The 44.3 piston in the 346 I just did is a white box 20 piston. All in the thread. Dang good looking piston.

IMHO it had better weight etc then the more expensive meteor afm piston that is most goes too.

Cheap and oem used shown. The cheap one was right close to oem weight. The meteor afm one was heaviest.

I agree, take a look in the exhaust port, that might tell the story. I had a MS 250 that either had an air leak or got straight gas somehow. The cylinder on mine was badly scored along with the piston. I’m not sure of the name of the chainsaw parts I bought, I think Hyway. That companies parts cost more, the kit I bought was about $100. I used them on the advice of a forum member.

Best I can tell ya. Pull them apart and see what all is needed.

If you go OEM prob wont be affordable to do but is a choice.

The saws are those strato newer plastic cased clamshell.

So I would either try and clean up the oem cylinder and use a aftermarket piston or buy a afm set.

Plenty of places to buy once you get them figured out with a list in US.

Repairing saws is easy and if your first time. Just take pics as removing to look back on if needed.

Pic I have saved of one of those apart someone was doing.

I think the 460 has more hours on it than I was led to believe.
Here are the pictures I took this morning of the 460

Hard to see but the cylinder wall has some shallow scratches.
There's ever so slight play in the connecting rod, first time I've ever dealt with a roller bearing on a connecting rod and I'm guessing that is normal for that style bearing?
Sorry about the dumb questions, as I said it's my first time digging into a 2 stroke and want to get it right the first time.
Thank you for the help

Long as play at rod bearing and rod is not up down movement. Thats a no no.

Side to side etc normal.
