I think that the advice Stihl gives is correct, don't run max RPMs w/o a load on a new saw, but break the saw in at WOT with the bar buried in the wood.

I always used to run 50:1, but this site has convinced me to go to 40:1. I also use high test (93), but doing that gets a lot of debate. The manual for my 362 said to use 89 or greater, and that higher octane helps it run cooler (a good thing).

Enjoy that new saw, should be nice.
Thank you for the advice mustangmike
 
So my MS661c arrived back at the dealer in Texas today and accourding to UPS, they picked up my replacement, the MS661R today at 5:00pm. It is showing a delivery date for Monday, which should work as my "weekend" starts Monday morning. Any advice on how to break it in? Should I baby it, or just run it like I would any other saw? How about oil ratios and ethenol content? Should I buy the premixed $8 quarts from the dealer for the first few tanks?
Run it. Mix fuel however you plan to keep doing it. Ethanol free is better since it has less problems for fuel lines and carb parts.
 
2nd 661R showed up. Here they are with the 36 cannon and 41" cannon lol If you have a full tank of gas and oil the 36" will not fall over. The 41 has a 404 tip which im going to change to 3/8ths. (why the chain isn't flush on the tip)

Painted the elbow on the new 661 black as well. just can't stand that white.

Why the hell would you care care what the color of the muffler was. It is a chainsaw. It is not an interior wall inside you house. You guys that buy 661s and saws of that size to cut cookies and put 2 tanks of fuel through the saw a year are pathetic.

Hey, this is a chainsaw enthusiasts website. What do you expect?

Whats pathetic is the fact that you felt the need to come in here and say something stupid like that. This guy is obviously a professional that takes pride in his equipment, nothing wrong with that

Fixed for accuracy
 
As previously posted, I am switching my 661 over to .404 and the Stihl site shows 104 DL for a 36" setup for the 661 and 108DL for the 088.
I am telling it here first, 104DL is too small and will NOT fit, 108 is too long and will not tighten the chain, I believe the 661 needs 106DL to have the adjuster work properly, will know for sure when the presets come in.
Presets came in, so back to converting my 661 to .404 ..............
I tried 106DL and then added a link for 107DL, but its impossible to get the chain on the 36" Stihl ES bar with the rim (on or off the saw) :dumb2:, and 108DL is too long for the adjuster to remove the slop. :angry::angry::angry:
So to run the 36" Stihl ES in .404, I ended up using 108DL and drilled 2 new holes in the bar for the adjuster (one for each side), and had to grind down the tail of the bar a little. :wtf:

Oil holes line up fine.:happy:
