Pics shown of a stihl 363 that been shipped over to US.
Is supposed to be carbed version of the new 400. But thats where it stops.

Stihl 363 open port cylinder and piston pics.

Then compared to the new 400 if recall right.

Checking out the neojunk clone H side carb for 3120. Never put it on saw and pump diaphragm feels like one I would replace when stiff.

Reason why a bunch of us swore off on this clone maker. They are way behind.

Farmertec non H carb works great. These neojunk ones are hit and miss.

No wonder folks have issues with neojunk clone carbs. Brand new carb and the diaphragm is stiff from get go.

Never had mix across it or installed yet.

It’s not even close to being pliable for pumping like Tillotson kit.

Inside round metal piece was bent alittle too.

neojunk 3120 8120 carb kit in their H carbs are horrible. I swear the pump dia in this is double the thickness and and stiff like a kit been run on emix

Just smh again this morning checking out the kit the new carb came with.

Overseas testing emissions on some newer saws.

Emission numbers of some saws I seen posted. =

Appears that the 564 XP uses clean air ports to “stratify” the scavenging mixture, just like in “strato” chainsaws with carburetors. According to data from the EPA, HC+NOₓ (or CO) emissions are comparable to those of “strato” saws equipped with carbs and better than those of the 500i.

HC+NOₓ[g/kWh]
564: 59.5
562: 62
7310: 55.6
572: 55.1
500i: 68.5

CO [g/kWh]
564: 252
562: 299
7310: 317
572: 225
500i: 406

CO₂ [g/kWh] EPA/spec sheet
564: 791/762
562: 763/778
7310: 749/743
572: 808/841
500i: 732/706

I’ve come up with 3 ways to run a spark screen on the Egan pipe for 2511.

One I like is done like PSS V2 screen in my 2511 cnc muffler.

Other way is outer with a clamp. John can show that style he does.

The other idea I was thinking on was at base of pipe. But didn’t know if spark screens should be between the pipe and exhaust outlet. Any feedback on that way?

I only did this to show for the guys that want the Egan pipe gains but have to run a screen in some areas.
