Pop ups and windows. Your thoughts.

[Mastermind]

The pansy part ain't directed at the saw owner......it's directed at the guy that is not willing to take the extra time, and a bit of risk to do a better job for the customer.

OK? Bye now.

I cut the chamber, not because it's easy but because it's the right thing to do.

I agree Shawn.

I also like the added control I have over the port timing.

For instance, on a lot of saws, I can lower the exhaust. I can make some of the older saws (think 262XP and friends) run like they would never run with a popup because of that.

How do you deal with too much intake due to dropping the jug?..

Is that Toms jug ?

 

[Mastermind]

That is a "Myth Buster" jug.

Spoken like a true former pansy.

Oh snap.

You are right though.

Are we the judged by who we were, are who we've become though?

I like having windows in my pickup, so I can see where I'm going.

I have a lot of pop ups with windows, thinking of going to a Mac.

Popups are for pansies.

You're fired Neal.

Pack your stuff.

Every Zenoah engine I have seen had a domed piston, but then again those guys are pikers and don't know anything about 2-stoke engines. I can't tell if the new 543 piston is domed though:

(From http://www.arboristsite.com/community/threads/inside-the-husqvarna-543xp.260309/#post-4886305 )

This is important as it is now a moral issue, and if 543's have domed pistons they will all need to be destroyed. Certainly all those GZ4000/4500 saws are all wrong and cannot possibly work, and their designers are evil.

I am amazed at the histrionics over a minor technical detail that maybe a dozen people on the planet have any interest in.

Is this the thread where we post pictures of cheese?

You are confused Chris.

A popup is not a dome.

This is a popup......note the obstruction on the crown?



Yes the 543XP has a domed piston, I just ported one. I still cut the squish band. It was far more complicated than a flat squish band......

 

[Mastermind]

The most important thing here is the ability to lower the exhaust port.......that is not possible when using a popup.

And component replacement in the future, if needed.
