Husky 350

[tallgrass_coyote]

My Grandpa came over this weekend gave me a husky 350 that is too much saw for his age. Said last time he went to use it he couldn't get it to start. It doesn't seem like it has compression. Pulled the exhaust and see some scoring on the piston. Assuming the cylinder looks similar.

My question is, is this something worth fixing? Everything else is perfect. Surprised it's messed up, he is a retired engineer and pretty meticulous.

Yes. Those are good little saws. Some people put 346xp top ends on them.

Yes, worth repairing! If you pull the cylinder off and check, you might be surprised, there might be minimal damage if any on the cylinder wall and then it would be just clean up and piston swap. Depending on the age of the saw or where/how it was stored, there might be an air leak, so might be worth pressure testing or even just replacing the oil seals as the others might be stiff and tired allowing air to pass and throwing off the mixture balance to cause the scoring.

It's possible that he might have loaned the saw out and someone else boogered it up. Looks like it might have been on of those where someone fired it up and immediately put it in wood without letting it warm up and the piston expanded faster than the cylinder.

This might give you a few ideas.

If it wasn’t a Husqvarna, I’d say the plating is fine, but their plating isn’t always the best.

Okay. I watched some videos, and other than the strap looks pretty straightforward. I'll tear it down this week and see what all parts to order. Seeing lots of range on price for rebuild kits. Don't know if I have the flat top or dished piston (44 vs 45) yet but the price goes from $20-$100 for the kit. Any recommendation?

If the cylinder cleans up great I would go with Meteor (if available) or OEM. If the cylinder is sketchy then I’d put in a cheap piston.

The biggest problem with cheap pistons are the pin clips, which are often weak and have large ears on them. Reuse the old ones if possible if they’re the same size or trim the ears off the ones that come with a cheap piston. I’ve never had problems with Meteor clips. I have had Husqvarna send the wrong size clips with a 395 piston.

If there is removable covers on the sides of the cyl. it is the dished 45 piston.

Well, you sorta get what you pay for… Chinese being cheapest and OEM being better and more expensive. You might get away with just a piston. Keep things as clean as possible during the tear down.
They are nice light saws worth fixing especially when they’re free

Update the intake boot clamp to metal if it does not already have.

 

[tallgrass_coyote]

Okay, cylinder and piston are out. I think the cylinder is f'd but I defer to the experts.



It's a 45 with the dish top. This thing is dirty. Might tear down some more to clean. Fuel lines are stiff so figure I'll swap those, also figure the carb could use some sprucing up while I have it apart. Open to suggestions for an engine rebuild kit, carb kit, and whatever all I need to swap the boot clamp. Saw price was zero so I can spend a little on it.

On a side note got quite the surprise at my wife's 10 week ultrasound....holy *s-word...

Congrats!!

I’ve seen worse cylinders. Run some sandpaper over it and seem how much is aluminum transfer that comes off.

Congrats on the babies!

It's always hard to tell from photos, but you might be able to salvage that cylinder.

With a saw that old, a carb kit is always a good idea, at least the gasket and diaphragm kit.

Kit the carb, use a 372 intake clamp. New fuel line. Clean up the stock jug and get a meteor piston. I had a quad port 45mm hyway jug run ok, but no telling if the next one would. Stick with OEM. As D said, you get what you pay for with the Chinese shït. Don't forget to pressure and vac test after assembly or you could be right back here in a tank or two. The sandwich below the jug has all kinds of spots for air to enter, including the cylinder risers that aren't always flat.

Congrats!!

Thanks, head is still spinning a bit.

So I hit it with some 500 grit, I can definitely feel a low spot with my fingers here below, and also above, the exhaust port. Not sure if the plating chipped off or what.

That’s definitely aluminum. Either transfer still on the plating or no plating.
