Since 3750 is sold. I ran and checked tune in ash.    Perfect for my area and my mix.

Storm came in before I could test run right behind it with same chain on 590. It's ready as soon as the weather clears again.

Just ran the 590 with same chain. Firewood round sized poulan feels better in cuts. With 20" buried on dawgs just a little the 590 has the torque advantage. Which I figured from get go.

Both were dry ash

I couldnt stand the factory tune that the stops allowed me. Pulled them both for fine tuning today.  Much better in the cuts now too.

It had a slight bog at transition I couldn't stand.  I couldnt open the L up any further due to the stop tab.    All better now.

For last year videos of testing a 54cc 60cc poulans and a 036 and later a 262 in poulan board.  I aint into videos much.

But if someone records todays testing at little gtg you might get lucky. But the 3750 badboy is gone to new home already.

Echo was already scored and pulling 140psi when it was ran this day. We didnt know that at the time.

The test wood was right in the echo 590 strong point. Bigger wood.   Little 357xp 56.5cc had a heck of a cut when I ran it. I never bogged it during the cut like I was most times.  Eric Nicol was making the fastest cuts 99% of the time.

 The ash was 16" wide and started at 14" tall and ended up 16" tall by 16" wide. So is what it is. Wood got bigger as we went so times would get slower. I told Eric this is why I use cants to test with back when I cared about such. In the end I said they all cut wood and and the wood never complains if it takes a few seconds longer in the cuts. The OE m-tronic 362 impressed me the most. But no way would I ever pay a new asking price for one.

Eric Nicol  thank you so much for the nice sized testing wood and the big bar testing wood you left for me too. The German beer is just how I remember them = very good. Wife tried it and said yep thats just how she remembered it out of those big glasses when she was there.

(((((((Eric Nicol posting Results are in on the 60cc saw comparison the cuts was in 14” ash but ended up being 16” at the finish so some of the times could’ve should’ve been a little quicker but it is what it is starting with fastest time Stihl 362 - 14.50 Husqvarna 357xp - 16.22 Echo cs590 - 16.37 my Poulan 380 - 18.19 Kevin’s 380 - 21.50 huztl 036 - 22.19 Dolmar 120 - 33.39 but the Dolmar had some issues so I’m sure it would have done better..overall a great day with good people))))))))

 Pics of the nice test log EN left me too. The one end is over 32" across in first pic. Perfect for the bigger saw testing I do before sending saws back out.

Others too

May pull the muffler today.  I read enough to see these really wake up afterwords.   
Might do before and after in square wood to see what was gained % wise.


Somewhere between these 2 muffler mods is what I am thinking.

 Andre aka andyshine has a good video for removing the limiter caps. The guy I got it from had no clue how to do it. This shows how easy. I didnt remove the carb to do it myself. I just removed the rubber piece that goes in for keeping dust out at the carb tuning area.

 Glad I pulled muffler for modding today after testing in the 8x8 with stock lgx nib chain. Dang piston must have scored from being to lean with the epa plastic stop. If I recall right I fattened it up as far as I could go when I got it and then pulled the stops this weekend. So saw is NOT for sale at this time. EN still was pulling 140psi and still runs fine.

What I went with for mm. I still went ahead and did the after video as it set even with the scoring and 140psi. Need to load the before and after videos after this.
