592XP info and a surprise

[redlight066]

It has a few common parts from the 390xp. Clutch, drum, and recoil. Not sure if the oil pump is a direct swap I didn’t get that far. Big end of the rod looked a little beefier.

the air filter let a few fines by in the tank of fuel we put through it. It may need a light film of grease around the lip. Ala HD2. Saw performed very well. This is a hot start saw. It does get heat soaked after several minutes. Fast idle start IS necessary. That’s about all I got.

Some nice pictures appreciate the information I like what I see
It’s nice to see that you got your hands on one that’s not fair.

Last thing. Saw went back with the rep. We should have a loaner/demo in a week or two. Honestly for a brand hammer new saw out of the box it’s a strong saw. Timing is advanced to the edge. We ran it with a 28” bar and all I heard was popcorn. I did make an attempt to hook it up to the diagnostic tool and it couldn’t recognize it.

Ok. One more thing. You can have the cylinder in your hand in 10 minutes or less. Carb box has plenty of room and the design is is brilliantly simplistic.

If you're a fan of the 5 series husky's, you can see a lot improvements and tweaks in those pictures. There's an insane amount of tweaks on those cylinder pics.
Might have to get one just to tear it apart.

Aight got to play with a 592 today and have a look see inside. Sorry I didn’t get any pics of the carb and carb box.

No crank stuffers? Interesting!

I wouldn’t want them on a 90cc worksaw anyway.

WOW pretty impressive looking. Do I see a alignment pin for the cylinder?

 

[RI Chevy]

592 looked and sounded good and strong stock. Impressive.

srcarr52 Are you taking any saws for port work? julios1580@gmail.com

No, I'm not taking on port work at the moment.

Interested in why you think that? 661’s have em and are really liked by lots here on the coast.

The 661 I rebuilt didn't have crank stuffers, and it was a fairly late model (production code December, 2019).

It did have the funny-looking thing for directing the charge up into the cylinder, like the 461.

I was thinking the flange that goes up inside the piston, my bad.

Crank stuffers are on the crank counter weights and it effectively is a “full circle crank”. Not having them shifts the powerband a little lower in rpm where a 90cc saw needs to be. Especially milling or with a long bar in hardwood.

I like having stuffers in the 572. It makes sense in a smaller saw that spends more time in smaller wood at higher rpm.

 

[Nutball]

I could be wrong, but in theory stuffers should always be better right? Port timing can be adjusted to provide the power curve you want.

Definitely. The smaller the case, the more charge gets pushed up. Move the power band down with the port heights

 

[kneedeepinsaws]

Does anyone know how this new quick start with no choke position works?

 

[CR888]

Mmmmm them transfers are big and need feeding, having a bit more case volume could be good for torque. What a sexy saw. Finally Tsumura have taken light weight bars seriously and made one thats actually light. It's a real bonus not having to spend a couple of hundred on a bar when buying a new saw. Stihl got their light bars right, looks like Husky has too. I hope that Purdy Tsumura bar will be sold in Stihl mount. I wonder whether the boss will include the 592 in Huskies latest 20% off sale.
