You're comparing modded 660 to stock 661. How many guys here don't MM their saw? If your 660 was stock, I might agree.
Brad, with the 660 having slightly more displacement and his muffler being modified, I still believe a stock 661 will beat it.You're comparing modded 660 to stock 661. How many guys here don't MM their saw? If your 660 was stock, I might agree.
Mine is coming from PA. Ryan was able to get a better deal on the r version than i could get on the standard model.... plus we dont have Rs here and I despise the big dealer here.Yep.......but you better get em quick. They had 8, I got 2 of those.
I believe you are correct. However, I also know how people are. People will see the difference being less than it really is and take it out of context. I simply think you're better off to compare apples to apples.Brad, with the 660 having slightly more displacement and his muffler being modified, I still believe a stock 661 will beat it.
IIRC, the rat trap baffle is still installed on his 660, and even if the baffle was removed, the 661 will still beat it

I have observed a 1-1.5 second LOSS in time by removing the baffle on my 461 and 660. Removing the baffle on a stock 461 or 660 seems to be a BAD idea.
Sound great, thanks, looking forward to it.
You must have a pretty good feel for how it is going to go after 15 tanks, but I'm looking forward to seeing the results.
well shouldn't a muffler should be at a certain temp to burn the gases or else you have carbon build up. As far as the 660 baffle goes. I look at it like this.
Stihl had the same baffle in the old 066 that they do today. My understanding is they had that baffle in the original design, even BEFORE the EPA regs. They met the epa regs by making the port smaller. ie. .625 down to .375. That's my understanding.

You do need some back pressure in most systems. Not all, but most. 461 and 660 seem to need it. You can get it from a baffle or you can take out the baffle and get it from restricting the exit port size ie. From what i can tell it's better to get the back pressure from the baffle and open up the exit port size.
