Sup crew!
First time tearing down a 201cm rear handle today. Looking to flap with the wise ones here on theory with this little tiny ripper.
I know they are fairly tapped out from the factory, but there is always room for improvement.
Here’s where I’m at;
high flow filter system
stock filter is a joke, crazy restrictive for the flow of this jug in my view. I’ll have some pics of my solution in about 1.5 weeks just waiting on some items to arrive. Should be clean and OEM fit
Timing advanced
3.5* as this is a 2019 build saw and I believe timing was advanced somewhere along the production run. My stock flywheel had a half sheared key from the factory [emoji43] any input on this, or secret sauce?
Muffler - the usual
Here’s some things I’m curious about;
Stock intake plate:
This sits under the air filter and seems to do a 180* shift then tunnel into the carb. I’m curious if Stihl designed this in CAD in order to increase air speed, similar to a velocity stack - or is it for emissions and air mixing?
I’ll snap some photos tomorrow.
Base gasket:
Stock base gasket squish - 0.0265”
Stock base gasket thickness - 0.019”
I swapped to a thinner paper gasket to achieve a squish of 0.0175” squish which I hope will be ok on the little 35cc saw
Has anyone played with raising the exhaust roof a bit or playing with any timing numbers? Would love if someone could share some ideas / constructive content [emoji1591]
