    I have several chainsaws that I have accumulated over the years. I have found them pretty easy to tune by ear then verify with a tach. Friday, oI picked up a 440e 2 at Tractor Supply. It was a return that I got for a good price. I know this is a risk so I got the TSC warranty. I pulled the plug and the muffler. Everything looked perfect. The saw cranks easily. I had to fatten it up a bit on “L” and idle it up a bit. All in all it runs well but when I tried to adjust the “H”, it seemed to always 4 stroke even when I leaned it to 13,000 rpm. I settled on 12,500 for a max. Runs and cuts fine. Warm restarts are perfect but I thought it odd that it always seemed to 4 stroke when revved up.

    One oddity that I noticed when the plug was out.......when slowly pulling the rope, as the piston came up and reached full compression, it seemed to drop for about 1/8th of an inch then rise again to full compression before it started its journey back down. It looked kinda like it was hiccuping. Is this normal?

    Is this a question about tuning or what the needle on your comp gauge does when you pull the rope slow? I'm corn-fused. Or what the piston looked like it was doing through the plug hole? :roto2nuse:

    Two things I suppose .........is the full time 4 stroke sound at WOT, normal and is the ( visually observed through the spark plug hole) hiccup in the piston travel normal?

    I am probably over analyzing. OCD I suppose . The saw does cuts well for what it is, but this is a bit different than what I am used to. Maybe an X-Torq thing?

    analysis paralysis. You have a good saw and are looking for something wrong? Quit already. The hic-up without the plug is the magnets going by the coil.
