He probably gave up after all the BS here.
Maybe he just found that his question was "loaded", based on the answers. Part of the problem is of course the sponsor/non sponsor issue - but who really would be qualified and willing to post a real answer anyway. Personally I know a little about who obviously is not the best (and why) - but I am not going to post that in the open! Also, the answer may vary with which saw model is in question....

One thing forsure I would want the combustion chanber cut and a flat top pistion. No more turned pistions for my work saws!
I totally agree, its hard to get another piston if need be when the piston has seen the wrath of a lathe.

How many guys think this thread is gonna stay civil? :msp_w00t:
theres not 2 squirts of piss difference in the performance a pop up and a flat top piston for most saws. some saws require a flat top to get the desired port timing and some work just fine with a pop up piston. if you do a pop up piston you dont have to do nearly as much grinding to get the transfer and exhaust ports back to where you want it. every builder on this site has done pop up pistons and all the sudden now everyone thinks that cut combustion chambers are the way to go. i bet i can build 2 saws and let anyone run them both and you wont be able to tell me which one has a pop up and which has the flat top.

I like the torque or pull of a saw with the cut chamber method.
Till you smoke both saws 1 with pop up and 1 with flat top. The owner can throw a stock piston in the one with cut squish and flat top and be back at it same day in little time.
That is the reason I got away from pop ups too. I dont own a lathe and never ever want to depend on someone outside again.
Not everyone can just go home and cut a pop up piston on a lathe and throw the saw back together in a hour.
I'm down to 1 saw with pop up and when she is gone all flat tops from there on.

It has done so far, barely?
Actually, I am more interested in what is going on with Jonsered distribution in the US, than in this! :msp_wink:
Interesting. I've owned a dozen saws with pop-ups and never had a problem replacing the pop-up piston with a flat-top piston.
Like Terry said- I own both saws with cut combustion chambers and pop-up pistons; running them side-by-side a person could never tell which is which.

Of all the saws I have worked on in the past with popups, a factory piston will hit the head at TDC, so the piston MUST be cut to work
I guess it depends on who and how they cut the head and piston.
JJ you know as well as I do that the ported saw will work with stock piston, but it wont be like it was set up to be with the pop up, psi, etc. Just saying. :msp_wink:
I like both and can not tell any difference like you say. I just choose to get away from the pop ups for my reason listed above.

I had two xpw's, two 2171's and two 2153's. One with a turned pistion and one with a cut chamber. I could tell the difference in the increased torque of the cut method. The turned pistion saws are quicker to spool up.
HERE WE GO!!!!! look up my old post "pop up pistons UNPRACTICAL":msp_w00t:
