Simple really. Echo got close to the same HP as stihl and husky but did it with a smaller bore and larger stroke. This makes getting the HP hard but makes for an engine that will like workloads better. It also means it will naturally be a tad off on RPM. So if it likes to work, let it work! My original plan was to fully port it and then go an 8 pin on the 24". After it took the 32" pretty much like it did the 30" and 28", I figured why wait. It turns out I'm not the first sadly, ran into a guy today who has an 8 pin and his is ported. That 15% added speed sure makes up for that RPM difference, and then some.
It does and I didn't know that, so I also changed that.
Yah , pulling a 32” bar with that saw is strain enough ... adding an 8pin rim is lugging it even more ... you need it ported first and even then an 8pin 24” is bout big as I wood go ... jmho ... Saw was meant to run at “x” rpm , 8 pin with 32” will cut no doubt but man what’s the point ? You’re beating the stuffing outta that 59cc stock saw with a 32” bar as it is (echo 16-27 recommendation) and now you are upping the gearing to an 8 pin ? That saws gonna puke it’s balls dude !
It's an Echo, not a stihl
Haha ! I agree !!! Look guy - we’ve all been down this road before ... if you want to rediscover the wheel that’s your prerogative......
We could make the assumption you tried a regular snub tail (husky large
Thanks for the explanation. that's 12.5%.
Painful? Like are you talking slow? I'm fairly sure you don't understand how hard of a cut that was for any saw. That perticularly oak sends a nice vibration down the bar on a regular cut let alone noodling. Even my modded 288xp wouldn't just fall through it. I guess it's my fault, I was looking for the hardest test I could for the 32", not simply a normal cut in softwood.
no I did not see video.
Whether Saw is an echo , STIHL or husqvarna the concept is the same ... you are exceeding the mfg recommended bar length and upping the chain speed by 14% using an 8pin sprocket on a 59cc stock saw ... you are also LOSING 14% torque sir ... your “idea” that somehow echo makes less hp but because of its design makes more torque I find fascinating! If you continue with your testing you may find that you will need echos “5 yr warranty” but will be upset when they tell you “not covered / poor fuel mix”. Go right ahead and continue your testing , after all it is your saw that you bought and paid for !
They do in the shop manuals. It's 45mm as apposed to the 562xp 46mm. I believe the Stihl is also 46, could be wrong its been a bit.
Considering I purchased it explicitly to play with it means I've already taken that into consideration. I hope it blows up, it will give me a reason to jump into the cylinder all the faster. Of course these days, echo pro saws are probably the most reliable available and most likely won't blow up. That can be a test as well. I guess they aren't into using their customers for working out their issues. I can think of some huskies and Stihls that had issues as of late on their release.
Mechanics who work on all 3 brands ; STIHL , husqvarna and Echo have told me STIHL outsells either competitor 10 to 1 and the saws in for repair are primarily echos ... ya get what ya PAY for my friend ! You wanna pay bills ? Run da ported STIHLS
