I don't like the kill switch. The choke will stop a saw just fine. It's way too easy to leave the kill switch off and flood your saw the next time you try to start it.
Echo CS-500P any good

I did basically like your bottom picture but just with a simple clip with tin snips and pliers to fold the flap out, left the flap to keep the exhaust going forward, the louvers on the side I left alone.
On the pump diaphragm it had the black but since it didn't run right I didn't trust it, felt stiff at first and was kinda grody on the carb side... I have a gross of parts on hand so all 3 were available but found the blue first in an open kit... brown is my preferred as well.
Yes, choke is a good backup for a kill switch, long ago I got in the habit of turning the kill switch back on after the engine shuts off so everything is ready to go when I get back to it then I check it when I go to pull it again... modern ignitions are stronger than the older stuff, harder to foul a plug...

Let this thing eat some wood today and had to adjust it, it's a hungry thing! It's definitely a good runner. Still have some tweaks to make and since I ended up about a turn out on the high needle I might change the pump diaphragm to a brown one... and check on the regulator lever level... although I think these needles are a finer thread than I'm used to, it was 4 turns out when I pulled the restrictor out...
@rangerfredbob H side 3 1/8 is stock carb setting out from lightly seated. For 490 500.
Fine tuning it after opening it will give or take.
Even stiff carb dias could caused being out to 4.
I dont know if 500 rev limited like 490 by coil. But somewhere in 12's is good on my ported 490.
Here is carb info from echo. They want ya at 11.4k in this. Mine 12ish.
Check plug after tuning right and running awhile for look see.

So how much louder is it after the muffler modifications ?
Not really very much at all. My dads stock poulan 3300 louder and stock 346 of mine louder still.
Listen mine is open without the restrictive pipe and opened front deflector like I showed.
The 346 sounds louder still with stock muffler. It got opened after this video.

Doesn’t seem to loud in the video.
My Echo is the 400, i would say it’s pretty quiet but it also doesn’t have much power, a 350 Husqvarna will make it look silly.
My main saw is Husqvarna 562, it’s way louder than I prefer so I usually wear helmet with eye protection and ear muffs.
Amazing what a extra 12cc of saw will do.
400 clamshell 40cc saw to the 350 52cc if the later ones and 50cc if early ones.
Owned a few 350 to know they dont compare to a 400 honestly. Not even in the same ball park.

I have no real reference on how much louder as I did that right off... but that said I ran a whole tank through it yesterday and don't think it was any louder than the 40cc Poulan I'm used to... other than it chewed better 
.
I don't have a tach, was just tuning to smoke and gave it enough to let it run right. Will pull the plug at some point after the next tank of fresh fuel...
