A bit, not as much as I would like (~1hr). I cut up some ~24in diameter oak I had laying around for firewood. Pretty dry. The saw barely noticed it was there and threw a nice plume of chips. A noticeable improvement over stock in terms of throttle response, rpm in cut, and the amount I could...
I just got my MS461 back from Randy. It was $450 shipped. He ported the cylinder (intake, exhaust, transfers), trimmed the base of the cylinder to increase compression, put an unlimited coil on, advanced the timing, modded the muffler, altered the carburetor (increased jet size) and added a high...
My back goes straight into my thighs. I wear a belt on my pants and suspenders on my saddle. That seems to stop the saddle from inching my pants down past the point of no return. I use a cheap "tactical" pair of suspenders and connected them to the webbing of my saddle with modified webbing clips.
Have you looked at larger cam cleats by Harken or Schaefer? The jet step is essentially a cam cleat you can strap to your foot.

For your 200t and 2511t I would run a nylon filter (that is assuming you're cutting green wood with them, your rakers are properly set, and you're keeping your saw clean). They are less restrictive on the air intake.
Nylon filters are: MS200T = 1129-120-1602, CS2511t = A22600214
I had trouble...
The last saw I had ported was $450 on top of the purchase price (including shipping). It depends on the builder and the saw (some jugs are easier to get into than others). I would imagine you'll be into it ~$300 to $450 if you choose any of the well known builders.
I set mine 0.030in to 0.040in depending on the chain. I also don't leave them as a large flat spot (like they come off the grinder after multiple sharpenings), I slope them away from the tooth so that the highest point of the depth gauge is a "peak" instead of a "plateau". I feel like it makes...
My plant pathologist wife recommended the stuff she uses at work to me. Zerotol (hydrogen peroxide and peracetic acid) at a 1:50 dilution, 70% ethanol or isopropanol, and/or 0.5% to 10% bleach to disinfect tools. Which disinfectant works best (and treatment times) are pathogen specific...
The carb on a 620P is a HDA-316 Walbro. SawAgain has it.
I agree with @dsptech, if it ran good (or at least good enough) with the stock semi-fixed H jet carb, I would clean and rebuild the original carb before I dropped ~$90 on a HDA-316.
You could always add an unlimited coil if you add the...
I couldn't get that style knee ascender to work with a Notch/Harken foot ascender. The rope would always sneak it's way out of the dual cams because the force on the ascender isn't parallel with the rope (so the rope is pulled out from between the dual cams).
I ended up going with a floating...

Bar stud removal is very simple. I have never had any issues with it. Use a little heat to break the thread locker. If you are worried about too much heat, you can dab a little vegetable oil on the base of the stud (as far away...
