Seems like just cutting the base for minimal squish would be an all-in-one improvement, moves both the int and ex numbers in a good direction.
Agreed!Most ordinary people just want a saw to cut wood with no regard for squish, port shape or performance of +/- a second or two... we here are an elite group of chainsaw freaks! People in second and third worlds have a great day just to cut wood, find gasoline and eat dinner.
I'm right there with ya Randy.And I'm all for it.....
My comment was to the I'd like to see a nicer finish and better port shape. I could care less about those aspects of the kit, I want to know if it runs well and functions as designed. I learned my personal opinion doesn't count for squat.
Same with cylinders...90 percent want a good runner. 10 percent want a good runner that's pretty!
There has been some recent press surrounding the 46mm Meteor Piston and Cylinder kit for the Husqvarna 50/51/55. I had a burned down Closed Port 55 donated to me by a good friend. As such, I decided it would be a good time to build this saw using the 46mm Meteor kit and provide an honest review of the product quality and out of the box performance.
Still wonder about the excessive squish...
Also wonder where the point of diminishing returns occurs when shaving the base for tighter squish vs. the effect on the port timing when doing so...., at least in the case of this particular kit. I'm hardly there yet on my understanding of two-stroke theory and hope the topic sorta evolves to cover that aspect here in this thread.
Tell Josh to put the beer can down and get to typing!Last time I checked, this was the subject and intended focus of the thread. Be kinda nice to keep it that way and let the man proceed accordingly.
Just sayin'...
Sometimes I wonder if compression is as valuable as we make it seem Poge.
The jury is still out on that in my opinion....
The reason I say that is I've had some mean Poulan saws which had bare aluminum bores and chromed pistons (3400s and some others) which run absolutely fantastic on 130lb of compression. 140 is generally considered stout for that series of saw.
Maybe we can get someone in here with saw building experience to chime in and talk about compression and how much difference 10-20lb of compression makes in the real world.
You know one without all of our fancy measuring devices just so we can "know."
Say you're at a GTG and a saw runs unbelievably well, is the compression a question or has the saw already spoke for itself regardless of what kind of measurement we want to put on it?
Obviously compression is an important thing, it's one of the big four that an engine needs to run, but if it's healthy do we need to get all messed up over a few hundredths of an inch?
Is compression really the all important thing in what makes a healthy engine, if good port timing and quality materials we're removed from the equation? Could the engine run well on 200lb of compression alone or is it just a piece of the pie?
I guess the question is, could I tell a saw, on the same chassis had 10 more lb compression, without the help of a gauge?
