Husky 359 mystery

[singinwoodwackr]

So, picked up an older 359 the other day... craigslist...
Looked ok, dirty but ran, idled, great comp but smoked bad.
On cleanup the piston showed carbon buildup above the ring and in the ex port...
Pulled the cyl to clean the piston.
Found weird pin holes in the inside of the cyl...bad casting?

Stamped # on the thing is 53270068_ and doesn't match any pt# I can find... aftermarket?
Cyl shows very fine cross hatching. No base gasket but a thing coat of sealer.

Piston cleaned up fine.
Comp before showed 180.
Was going to just try new gas and run it until I noticed the car ones piston.
Pics...
Thoughts?

Picked it up out of Sweet?

Yup

I know some Huskies had crappy plating like that for awhile, you might just have one of the bad ones. I'd just run it till it blows, personally, and maybe use Husky or echo mix oil.

Do you know who did the obvious "work" on the cyl?

I do not.

The pin holes are from bad plating prep.
If it makes 180lbs of compression I would run it.

the summer saws smoke a bit more, to keep the mosquitos and ticks away.

Looking more closely under magnification light at the obvious port work now. Actually some good work.
One builder I've sent picks to thinks that number on the base of the cyl is the builders stamp, not a SN. There is no husky SN starting with 532.
I may have gotten lucky on this one

Carb is a walbro 199A.
Should be a 174 or 175 according to specs,. Or, different OE carb than shows in the manual I have...
Interesting

Who did you buy the saw from?

 

[singinwoodwackr]

A widow in Sweet.
Her husband had a few other Sthils but none I was interested in.
A 390 and a 180.
Also had an old 064 Grandberg setup that needed a lot of love. I have that size so didn't make her an offer.
Her brother was helping out, seemed to know more about the equipment than she did.

A Walbro 199A is correct for the 359, at least I know some were factory equipped with that carb.

Yea, just found that out. Used on the 357xp as well.
my manual only showed the other two.

The number stamped in may be the part # of cylinder that Husqvarna uses internally For production As you can’t buy a cylinder by itself, but they need to know what part it is for cylinder kits or manufacture
a lot of parts have numbers on them that don’t exist to dealers end users etc.

Ha, thanks. Good to know.
It would still be cool th find out who did the port job, especially if local.
Whoever it was knew what he was doing...nice mild porting, nothing radical.
I'm surprised, however, that he didn't do the muffler. That will definitely need to be done.

Sure it was ported?

Yes

Could have been the deceased owner as he rebuild old cars and seemed to know his way around motor builds

Somebody has a damn steady hand if those numbers aren't factory haha. Perfectly spaced and level, definitely looks factory stamped to me. Husqvarna made the 359 cylinders in house. Every one of them I've been into had those "pock marks" in the cylinder plating. Depending on run time or more often sometimes "sit time," some are pretty bad. Pretty common. Regardless, they rarely seem to effect runnability. They came with either the Zama EL42 or Walbro HDA 199 carb. Others say differently sometimes, but I'm partial to the Walbro. Once they're gone through and debugged, they're a phenomenal carb.
