Dr. Hackemoff, you will experience your most increase in cut times buy swapping out that darn safety chain and replacing it with 72LG or something comparable, i got a new MS660 this week and im gonna run about 10 more gallons of fuel through it before i take the core out of the muffler(only got about 3 gallons through t so far)
 
I haven't seen that in the compression numbers.. Where did you get it from? It would be a problem to run a saw on 87/89 at 13.9.


The stihl service manuals from the mid 90's show both the 064 and the 066 at 10.0 compression ratio.

Hi all. I have a foolish question. I owned a couple of the 064's a few years back and loved 'em. I have been running Huskies the past few years. Now I am contemplating buying another Stihl. I am wondering though, what are the differences between the 066 and the MS660? I had run an 066 a while back, and was impressed. I have been looking on ebay, and can get one for about half the price of new. So, I am looking for some advice from all you guys experienced with Stihl. 066 or new ms660?


The biggest thing is that the numbers are totally reversed, and 660s tend to be cleaner and newer. :laugh:

We had a gentlman come in today with an 029 and proclaim that he got it on ebay for "only $325.00!"
Should have seen the look on his face when we showed him the price of 299.95 everyday.

That auction fever will getcha!

Man, I would NEVER buy a chainsaw without being able to take off the muffler and inspect the piston and cylinder. Especially a low end saw like the 029 where you know it was run by someone who rarely uses a chainsaw.
 
Stihl 066 MS660 Cylinder & piston 1122 020 1202 $292.02 1122 020 1203 $312.91 1122 020 1204 $252.33 1122 020 1208 $272.51 1122 020 1209 $361.90 1122 020 1210 $272.69 1122 020 1211 $361.90 1122 020 1219 $268.30 Any idea if the 1209 & 1211 are the same. The 1209 has a footnote saying it is an old prior # changed over in 98. Im speculating the MS660 1211 is the same as the Mag series 1209 but in looking over Deans post here #24 it may be a horse of a different color.
 
I'm guessing the first one is for the red light version. The other choices must be with or without the compression release.
 
After researching the subject I went with the 066 w/ poly flywheel. Remove the inner box completely & install the dual port front cover crank up the fuel delivery & the thing will be right back to where it was before the EPA put a strangle hold on it. There was also a 066 model that was made in Brazil it will be stamped into the starter side cover. Cant remember exactually why but the red eye & Brazil models are not the ones you want but recall somethin like the bottom end was'nt as strong. On the poly flywheel it is not 100 % poly the center is still aluminum & is 30-40 lighter than the solid which makes the saw spool up faster. :chainsaw:
 
If you are going to be running long bars on it there is also the Stihl Australian High Output Oiler . Complete pump HO # 122-640-3201. Around $ 68.00. This was also a bottle neck on the 066 that can be improved upon. That part is not in the US book. If you want to confirm it before ordering call Stihl Customer Service at 1-888-784 8575. Dont beat that # to death with questions that can be found here or they will pull the plug on it & will lose the ace in the hole. I dont give a rats ass as my saws are finished . Hope this helps.:deadhorse:
