It would have made sense to run the Drum/spur until it failed. But it does have a slight groove in it currently. There isn’t a whole lot of other benefits to it that I know. The saw really doesn’t have the balls to run an 8 pin in my opinion. Rim sprockets are cheaper that’s about it. I would not recommend what I did 2 drums ago and run it until you can tacitly feel the spur disintegrating/chipping while cutting. Live and learn, I now tap out my air filter and grease things that should be greased and sharpen my chains fair more frequently. The main reason I am using this saw is because I found 10 18” .325 68dl chains. I sharpened all of them and I’m using them up. Cheeses me off that these chains are the wrong dl count for many other saws. I think 72 is the more common non proprietary dl count. Don’t have a breaker spinner yet… How much? I’ll think about it.
I did the rim sprocket on my MS250 when the spur started going. After doing the timing advance I tried an 8 pin. Don't see much difference in cut times when bucking, but I like the higher chain speed when limbing, cutting grapevine, and other invasive species out in the woods. I also think the rim sprockets last longer than the spurs, but I've not kept track well enough to know that for sure. That 250 has cut a LOT of wood over the years.
Is Stihl propitiatory or are the rest of them..... $350. Thats what I paid for it. There will be shipping on top of that or delivery to Denny's GTG.
You go full Monte on one yet? They can be ported ya just can't adjust the squish / compression without a lot of effing around.
I haven't been inside it yet. I figure I'll wait till it starts getting light in the loafers. It runs just fine with the muffler opened up, jet limiters removed, square filed chain, and timing advance. When the time comes, I'll re-build it and port it although it won't get any serious machine work. I had been WAY inside my old 391 farm boss years ago and it was a clamshell. When I sold it, the guy that bought it bout ripped the pocket off his jeans to get his wallet out. I cut a couple cookies off a 20" Sugar Maple log and his eyes got as big as pie plates... He had to have it... LOL He said he never ran anything other than a Walmart Poulan that he fought to get started every time he used it (kinda like me before I found this group). He thought that Farm Bosses were the best saws made. I had cut a lot of wood with that saw too. I don't miss that overweight thing that my brother had put a 25" Super bar on it. That thing was HEAVY.
I've had great success getting gains from clamshell saws. My BIL uses a 310 and 311. Also super heavy.
I cut some white oak limb wood this afternoon. I haven't used the MS-362 much this fall as it's had the 32" bar on it most of the time for some big stuff I've been working but haven't had much time to get to. So anyway, I put the 18" bar with an aggressive square filed chain on it to hit this dead limb wood. That was fun!!! white oak up top, maple in the middle, and cherry on the bottom
I'll have to pick your brains on port mapping once I get a wheel on it, someday... I've seen some of your cute little tiny saws rip through wood punching way above their weight class... I've always been kind of a "small block screamer" kind of guy. I had a couple buddies that were into the big block stuff, but that was too rich for my blood... I'll be retiring in a couple years and I'll have time to play more.
I just get lucky I guess. Less is often more I've stumbled upon. As far has duration goes. I do like to play games with the pistons. Lightening them ect. Velocity stacks and free flowing filters.
Velocity stacks optimize smooth airflow. Sharp edges and corners can create eddies that create resistance. Vortex swirls in the right places are beneficial, but would be tough to place without being able to visualize them or have a great computer model for them. Some of the plastic intake tracts have the little triangle bumps in them that actually lower drag through them. How exactly that works is a little over my head. I understand basic airflow but when it starts to get deep, I get lost quick. Has anyone ever played with a boost bottle on an intake of a chainsaw? I have one on my blaster and it did give it better response in the lower end and mid-range. Sorry for the brain dump... I ramble on at times...
