Chainsaw Repair

Reading on the CS-8000 today because of this thread. I could never find any information on the max rpm out of the wood. Anyone know?

I really wasn't impressed my Echo 8000 at all, the throttle feels disconnected, the saw doesn't like to rev and I didn't find much difference at all after I ported it.

  I just got done flogging the JD 800. Holy chit man. This thing had throttle response like my woods ported 7901 had.  As far as I know this one is muffler modded and with a tighter squish. This thing was hauling balls at 14K.  I would swear it was woods ported but it was traded in as a stock saw.
It flat out ate my Poulan 505 82cc up in the cuts and was excepting it to eat the MS660 with muffler mod. I will give the 660 the edge, but someday I will time then in cuts in small wood and all wearing the 8T's again.

The idle sound  and muffler mod sound in the cut on the echo 8000 was the best sounding today too.

I would love to see what the porting looks like.  What is your compression Kev?

All I did was gas it up and run it today. Suppose to be stock porting with tightened up squish.  never been inside to know what a echo 8000 looks like.

All I know if this is stock porting with just squish tightened up. I  LIKE! 

Sorry no pics, I had the saw tore down for nearly a year before I finished the porting and put it back together. That probably worked against me too. I might get another one and try it or play with this one a little more and try again before I ship it off, I would feel better sending it away if it ran a little better. I did a pretty conservative port job, just widened slightly and put the transfers down into the case.  Anyways I compared the stock video (youtube echo 8000 it is the only echo video on youtube under canadiancarguy) to the ported video (photobucket echo 8000 also the only echo I have on video under canadiancarguy) and I guess there is a difference, but not what I had expected. Still could be lots left with some toying around...

Finally found a pic of the early 8000 hand guard that would be on the JD 800.  The later ones appear to have had the chain brakes in IPL.
Think I might just try to retro fit a poulan hand guard or nothing at all.
