Bought the 400 fall 2021 and have maybe 20 tanks through it and running the bark box, saw does well but one big complaint that’s driving me insane is a hesitation from stop to full throttle right when hitting wood. Only a second but damn it’s annoying. Anyone have any insight on that?

Mine is like a gun shot. Pull the trigger and instant boom. Reset?
 
Finally got around to getting the oiler upgrade done this morning. Also stiffened up the AV a little. Put the 28 back on it…. Absolutely perfect. Runs tank per tank oil to fuel now and oils the bar just right.
Been waiting for you to pop back in and give an update on your progress with the 400.

Did you make anymore changes besides the muffler mod to the running end?
Did you do the reset after ten plus tanks of fuel?

No, just the muffler. Oiler upgrade and a stiffer AV piece for the underside of the saw. I didn’t reset anything intentionally just kept cutting.
 
It is impressive you can pull a 28" bar power wise with that saw. I can get My 460 to bog burying a 28 in hard wood under the right circumstances.
I guess it’s just what you expect from the saw. My 395 will bog in oak with a 28 if I’m heavy handed. My opinion the 400 has plenty enough power for a 28 based on what I expect from it.

Outstanding! Like your personal touch on your saws...No one can claim that they aren't yours 😁
How did the oiler upgrade go, pretty straight forward I presume?

It was. The little O rings on the cam thingy were a real PITA but the rest was strait forward.

Edit: cam thingy: control bolt

I called WCS and asked if they would make a fallers kit for the 362/400 and was told no plans at this time. So I took a chance and ordered the kit for the 462 to use the little yellow star shaped damper bushing that goes on the underside of the saw. Much stiffer and fit great, makes a big difference.

Unrelated, but I had fun last few days with an order for lumber that gave me some time on the sawmill.
