Goin into uncharted territory?

 

[CR500]

Definitely looking forward to this.

J my 661 is no slouch lol, it may not beat the 064 but the saw certainly can pull a 28-32 bar quite well.

I have been able to fine tune a couple round ground chains for it and it pulls quite smooth.

To me the064 looks angry while the661 is very broad.

I'd like to see an original stock head to head comparison between the 066 and 661.

The 066 had such a variance in port timing it would really depend on how good of a runner you have stock. J has a stock 66 cylinder that I bet would give a stock 661 a run

If someone is going to take the time to find an 066 ringer then I'd say it would only be fair to do the same with the 661 being used.

Yeah, I'm just sayin it would be luck of the draw, you never know what your gunna get with a 66

A 661 is pretty consistent on how they run but a 66 can vary a lot.

Put a better chain on the 661 and it was much better Jason.

Turns out I had an off day while filing and did not leave enough hook in the cutter, grabbed a chain with decent hook and it just sliced through that maple log I have.

Amazing what a little hook can do in a chain lol

I cut timber with it several days and liked how it ran. Very well mannered ported saw

Has an angry side when you need it and a conservative side as well

It's a stihl that's why. They are tough as nails.

Wow, you sound just like the owner.

Ive timed 4 stock 661s. They have been very consistant. All within the last two years. Of course thats a very small time frame.

 

[Chainsaw Jim]

It's good there's some consistency with the 661. There's not much worse than knowing there's an equally valued better version of what you paid good money for.
This brings up another question...how many different castings were used for the 066?

 

[jmssaws]

I don't know if I ever seen 2 066/660 cylinders alike

 

[jmssaws]

Seen the exhaust from 93 to 99.5

 

[RI Chevy]

No problems here. We just send em to you guys to make em better and stronger than factory! LOL

Ha-ha ha-ha. Funny funny. Still haven't gotten that intake boot on. I've been torturing the 390. It's slowly becoming tolerable.
