Didn't anger any neighbors today. Only ran the lawn mower and the Husky SD22 overseeder. Then over to the girlfriends to paint her gallery for an upcoming show, and let me tell ya, I'm not all that fond of painting. Then to the hockey rink for a pre-season scrimmage which has this ole boy tired, sore, beat up, and worn out.
Main differences between the 920 and 930:
Air filter and covers. 920 has the single screw down through the top and filter to hold them both on. 930 uses the 630/670 filter which is held on by it's own two screws and does a much better job of sealing out the dust. The filter cover also has two screws of it's own.
Top cylinder AV mount. 920 uses rubber while the 930 uses a spring.
Cylinders. Both closed port, but the 930 is open at the bottom to the cutouts in the crankcase very much like a 372, which is a more effective way to go about it. The 920 is like a 670 or 272 with fuel only going through the piston windows. The 910 also had the open to the crankcase porting like the 930. Don't have any idea why they got away from it with the 920.
That cylinder difference is why a 930 will generally out cut a 920. I have two of each, and the 930's are both stronger than the 920's. Official max RPM's for both saws are 12,200. I usually run mine up around 13,000. Never thought about going to 13,500 before. Hmmmmmmm. :msp_sneaky:
