Is this the 461 build thread?
Good sir. How about you?
You gonna be alright, ChiefI'm gonna survive Jeffus.....maybe.
I think that was the 880. But who needs thoseWas the 461 Stihl's last non-Strato saw?

Seems like the fuel mileage improvement with the 461 vs 460 is mostly due to the quad porting design of the 461 then?Neither the 461.....661.....500i....or the 880 are stratified engines. Regardless of what they say.....
The timing events on the saws they refer to as delayed scavenging engines doesn't mesh with that actually happening to the extent they would have you believe.

The muffler opening is tiny. The transfers are canted in such a way that back pressure created in the muffler can back feed into the uppers. Plus the jet in the carb is small. The coil is also different. Ignition timing could be altered to help with fuel economy.
My point is just this.....delayed savaging is at best a gimmick. And.....it's a dirty way to purge the hydrocarbons.
