Oiler can be modded by swapping the piston, and tank size difference is negligible. You can't lighten up a 46 case to weigh the same as a 44 case. Been running hybrids for 16 years, I don't grab the 460 very often.

Long time land management guy, though on the wildfire side of things up in the Pacific Northwest. When my wife first saw the XCU06, she got all giddy about how cute it was and wanted one. I obliged. That saw gets grabbed off the rack more often than any of the other saws. Limbs, little jobs...

Loose tolerance between the wrist pin and piston would be my guess if we're skipping talking about metal quality, especially given middle-of-the road compression.

Yeah, the premise that overspeeding the chain causes this problem isn't real valid. In that case, a ported saw would "out run the tip" because it holds more RPM in the cut. 9 times out of 10, the chain derails from the heel of the bar, then comes off the tip. Now, bigger sprockets make this...

I can't tell you how many saws I've done this on, never spun a flywheel, never had it move from where I set it.

That's the gospel right there. Bitter cold air can't hold as much moisture, thus icing isn't as much of an issue. But 32 degrees air temp when the dew point is 35 degrees? That'll cause some icing. Icing can occur when the air temperature is a little above freezing as well, due to the drop in...

Here's how I did mine, about 30 seconds with a cutoff wheel. Agreed, put the extra area low where you don't melt plastic. No idea if it added power, did this before even firing it up.

I grew up in a logging town in Western Washington, fell my first tree at 12 years old. I've been running saw professionally in the woods of the pacific northwest for 21 years. I have been responsible for certifying the top tier of fallers for my employer for 12 years. Your use of eastern...

Yeah, that's some high grade, hard stuff. What does the sprocket outrunning the tip mean though? I literally can't make sense of that collection of words.

What do you mean by this? I've never had trouble boring full length with long bars (28, 32, 36) and 8 tooth sprockets. Not saying your experience is invalid, I'm just saying that in my cutting conditions with my saws I haven't ever had mechanical problems boring, so I want to understand your...

All of my normal sized saws are ported, the 44 hybrid, 460 and 7900 usually wear 25", 28", or 32" bars cutting in softwood. The 32" bar gets a 7 tooth on those saws, 25" & 28" get an 8 tooth. The 20" bar I have for the 7900 gets a 9 pin. My 660 can pull the 36 with a 8 tooth no problem, but...

I've had wobble from just the slightest bit of grit between the wheel and washers. For me, just wiping the 4 surfaces clean and reassembling has taken care of it.

Madsends huh? Never heard of em. Madsen's is a great shop tho, grew up not far from that chainsaw candy shop.

So let's assume that the HD does restrict flow vs the standard setup. Now, let's expose both of those setups to the same amount of dust and run em on the dyno again. Back in '08, when I still had the standard setup on my saw, I got halfway through the face cut on a 36" red fir (first tree of...

Max flow FTW. Cutting on fires, the OEM filter clogs enough in 1 tank to start bypassing the filter and pull dirty air past the seal. Never mind what crank bearings look like after a few years of running stock filters on fire. Never had dirt get past a Max Flow. One trick I figured out a few...
