From what I've read there aren't a lot of people that are a fan of the 100:1 amsoil advertisement around here. Saws also tend to generate more heat especially saws that aren't cleaned regularly. They not only have the engine, but they have the clutch and bar and chain all very close that will generate a lot of heat. Add that to having sawdust and crud caked in the cooling fins and that's a bad combination for 100:1. Most airplane engines not only have the air from the flywheel but they also have air moving from the speed of the plane as well as the prop making it much cooler. They also generally run at a more constant rpm making less heat.

Agreed. I was more curious if they get away with 100:1 because of the thickness or concentration of ingredients in the oil. They advertise running that oil in all sorts of 2-cycle engines but I have only used it in the airplane motors because it was recommended by the manufacturer. They have changed their recommendation to Redline so I won't be buying anymore Amsoil 100:1. If you're curious, these aircraft motors are pretty slick. They are electronic ignition with no magneto. We use a 2400mah 7.4V Lipo pack per 2 cylinders to run the ignition. The battery lasts about 10 flights or so. The 4 cylinder motors run 4800mah or 5200mah packs. The ignition receives CKP from a hall effect sensor on the crank hub.

Possibly, but I doubt it. They started making the engines in 2000. Back then there wasn't much synthetic 2-stroke oil out there. Amsoil was one of the first to really push it and they bought on to it. But it's not 2000 anymore.

That's pretty cool I used to fly some rc stuff but they were all single cylinder glow plug engines. I've read people using amsoil saber at 40:1 even with good results and no carbon build up. It's good oil, people just don't like that they advertise 100:1 I think. If the engine fails they more than likely won't cover you and the manufacturer definitely won't because your half the oil they recommend amsoil or not.

If you guy's are interested I'll post a few photos of the 620p while I was cleaning it up today. I don't have anymore cutting planned for it for another week or two so I thought I would clean it back up. Under the side cover is all slicked up painted magnesium except for the little brake cover. The side cover is obviously magnesium as well, with a nice rubber pad at the rear that pops right out if it get's tore up. The last photo is of the saw put together with a 20" PowerMatch bar and Super 70 chisel chain while sitting next to my other favorite little screamer, the CS-355T with a new 14" bar to replace the stock 16" most of the time. That little saw rips with the 16" and I've yet to cut anything with the new 14" but I bet it will pick up even a little more speed. The only drawback is that it is super loud. The muffler is just an empty can, and I haven't touched it.

Looks like a 590 with some fancy parts on it. I'd like to try one some day but for now the ported 590 for less then a new 620 will have to do. Deffinitly want a 355 sometime soon.

I run Motul synthetic or Echo red armor. We used to call it dirt bike blood back when I was riding.

So I was in HD and they had a used like I'm talking cut wood used and returned cs590. So I figured OK it used I'll buy it. Ha ya right I had to bicker with them to even go 25% off so I didn't get it. 300 bones plus tax for a used 590. I even showed them that I can get a new one for that. Crazy.

My first one came from there new but I also needed at 8:00pm for an emergency. When you need it you need it.

Picked up a 620p. Dang this thing can cut. What chains are y'all using? Particularly for dirty wood.

I don't cut much dirty wood, but you'll be better off with a semi-chisel for dirty wood. The saw comes with the full chisel. Depending on the size bar you are running, the semi-chisels are sometimes not easy to find from Oregon. I'll look around in a minute and find a part number for the chain. What size bar did you get with the saw?

 

[Banshee365]

If you got the 24" you need an 81 drive link chain. Oregon doesn't offer a semi-chisel chain in at least the 20" and 24" PowerMatch bars. You'll need to go to another brand. If you want to go with Carlton/WoodlandPro you can get the 30SC81 for the 24" or if you like the Stihl chain you can get the 33RM8 Rapid-Micro chain. For really dirty wood I would go pretty cheap on the chain. If you were cutting lots and lots of dirty wood I may even look for a cheaper bar to run a cheaper chain on and not tear up your PowerMatch bar.

72dpx from Oregon. Any decent saw shop should have it either in loops or from a roll that they can make whatever size loop you need. 20" bars are 70dl and 24" are 81dl.

I know you're a guru around here so maybe you can answer this. Why, in Oregon's part finder, does it not show a 72DPX chain for a 70DL bar but when you search for 72DPX070G they are all over the place?

 

[7sleeper]

You already answered your own question. @fordf150 is a chainsaw guru but not a computer guru...

70 dl is odd duck when r.o.t.w runs 72. D009 mount will work on echo. If you have other brands you can run the same dl .

Don't forget to grease that clutch bearing

 

[PecanGuy]

Thanks, it is a 20" bar.

Banshee,
Oregon makes the bars, chain and sprockets for Echo. They also make the same stuff for others. When they do this, they promise to send business to the OEM under a non competitive clause in their contract. This means they do not list the bars, and chain that they make for the OEM on their parts finder fit up thingy.

That makes absolute sense. But, there isn't a semi-chisel available from the OEM, at least under the 620P parts list. I suppose Echo only wants you to run full-chisels on their PowerMatch bars, maybe for cutting speed against the competition?

More like listing every combination would just confuse customers.

They pick what they think will satisfy the majority in the majority of cutting situations plus meet kickback standards. Echo sends them out with lpx chain and I honestly have no idea what they have available for chain....I looked at prices once and never looked back. Why pay double just so it can come in an echo box instead of Oregon.

Glad I'm not the only one who appreciates the
