The SCARR Husqvarna 592XP build thread.

You could if you mill it it seems.

Setting these up on a mill would be pain.

When on lathe do u have too do all the way across base can you leave a 1/4 where impulse is since it dosnt mate to anything on case

But the same distance out from the bore on the opposite side is in the transfer mounting surface.

did 592 and 585 come with 7 pin rim from factory

Yes, both 3/8 7 pin rims.

What was it stock?

Don't you have one you could test? Lol

Maybe......if I had a 10mm extended type gauge I trusted.

125-130 psi, they are abnormally low compression.

Wow that low, Sounds like a 1950's and 60's power products motor used in a lot of vintage chainsaws.

Well ok then

The stiff spring on the Schrader will cause the lower reading

Yes it will, the amount of psi it takes to open the spring is the amount lost on the reading

I believe it's about cooling the cylinder at its hottest point, the exhaust port with the incoming fuel/air charge.

Smart!

Some pics of the 585 porting.

The exhaust port grew a fair amount. I use a mechanical pencil to trace the port onto the piston so I can validate the shape.

Did you post a pic of intake flange before machine work Shaun?

Nice work Man.

Comparing the cylinder, again 585 on the left.

All the ports look of similar shape and size (ratio to bore). The transfer lowers are pretty much identical, of course the bores are different sizes but so are the skirt extensions. So the 585 skirt extension is floating around in the case. Both exhaust ports have an identical wave pattern in the roof. The 585 intake port is rough cast while the 592 port is smooth like it's been machined. You can see the stock squish measured at 0.023" and 0.022".

Not sure why I cant quote Jeffs reply but thank you.

It's because his reply is all quotes from other members, he didn't actually write anything that you could quote.

It looks like the strato ports are wider then the tract of the intake width?

Optical illusion I believe. Camera angle vs near/far type thing

They are not wider, just the camera angle.
