It ran not to bad considering , no head , stock bore carb and stock piston but it is on alcohol, if I ever build another one it will have a different piston in it that is forsure , those thick 395 rings donot like that high of rpms

Was just reading about jonsered 2094. As you know I sent a 2095 down the road.   To refresh my mind

hi all. its good to see some names i have not seen for awile.most of you don't know me but maybe that will change in time.

just to claify a few things about these two saws. 2094 was built by copsy as a good work saw, as far as i know it has a pop up piston.
the 660 i built. there is no popup piston. piston is stock, unaltered. infact the only things that are ported it the cylinder and muffler. this is a woods mod saw, not a high rpm saw. i think it was 40% faster cut times in bigger wood.

the 660 is by no means a race saw but runs real well.
the 2094 looks sick, but i think its the porting.
latter scott

Info I was looking for.

Just to touch onwhat Scott said, actually the 2094 does not have a pop up piston.  Atleast Eric Copsey told me she didnt.  It cost me 250 bucks.  I should have never let him touch it.  She will make her way towards Scott after the build off.  I honestly believe it was a hack port job.  Time will tell.
I certainly dont expect Scott to make her as fast as that 660.  he may not be able too.  Depends how bad Eric Copsey screwed her up.  I will also say that 660 Scott did is exceptional.  I know of Scotts saws takin more than one 394/395 in a race.  I cant wait till he gets ahold of the 2094.

The guy that got the jonsered 2095 said he was probably going to port it once he gets everything for the split and rebuild. 

Is there better videos out there on the 2094 2095 ported? Known good ones.
Seems this ecsaws 2094 in this thread was a flop.

Not many on YouTube. I need to get that saw and put the other stock top end on it.

Now I'm curious... I haven't run my 2094 in a few years. Last I did I seem to remember it ran under load a bit higher RPM than that one did. Twisted like a 372. Wound it up to 13,500 No load. All it had was squish set to .018, a muffler mod (Gutted with a 3/4 in tube), and a little more duration on the intake. That may have been the one I struggled with because of a limited carb & eventually swapped it out...or was that the first 820. Can't remember anymore. I quit running it as it was a biatch to pull over and start & felt like the pull start was one step away from coming apart. Hardly a modded saw but it was really strong. BUT time tempers reality. So it needs to get some video/timing and compare it to those Aftermarket MS660 saws. Also hardly modified saws but a reasonable reference. Doubt there will be a 3 to 2 cut differential in a test log of hard maple. Just curious. Would be curious on how fast the 2094 picks up RPM's.. Mine was lively like a crisp 372, just bigger and more of everything. (Including vibration and weight)

This might simply be a verification the one building that 660 know his chit.. That's my bet.

I take it the 395 and 066 was both ported. Do you want to share who ported both saws?

 I just watched a ported 395 cutting small 8x8 wood on youtube and I wasnt impressed with it (video was only 6 days old). 

Dang it man will somebody show me a 395 that will cut and live up to the talk I have always heard over the years.

Now I know you probably not into this. But how did they do in cant type racing in 10x10 with bigger gear etc.

I know my 066 which I only ran 32" on though.  Also was a heck of a cant cutter too for gtg racing.  Nothing special either. Just stock piston with no work, no squish cut, no pop up etc. Just good ole porting. Was so good a porter north of me in Ohio wanted my saw to get the numbers out of.

This was just in 8x8 but each bigger gear she was faster and kept pulling.  This was just using a 8T and set fat at 14K this saw like 15's for cant racing.

They'll pull a 10 pin fine but I need to make a custom bar to keep the chain on. Even a 9 throws the chain once in a while.
