Post number one thousand, seems fitting.

I purchased two used 394XP's out of Canada and they arrived today. Much to my surprise they have both been Walkerized.

From the initials dremeled into them, they both belonged to the same chap. One is a 1992 vintage, the other a 1994.

The ad stated that one would be good for a firewood saw and the other needs at least a set of rings.

I didn't have a 404 chain for these, but I fired them up anyway. I have never had anything bigger than a 76cc saw previously, so I was excited to hear these bad boys fire to life. I chose the better looking of the two to go first...........but wait.........I want to test the compression cold.

This is no mistake, the Lisle has tested a dozen saws recently and it is pretty close with the numbers.

The higher compression one fired on the fourth pull and holy mackinaw Batman, what a sweet sound! Sounds like a top fuel drag car at idle and revs like a broken in 346XP NE.

The other one has 125lbs compression and took roughly twice the pulls, but it fired with authority. It doesn't seem to have nearly the snap of the other one, but it runs pretty well. I pulled the muffler and the piston/cylinder look fine. Rings should bring her back.

Odd thing, both saws have identical breaks in the crankcase housing right to the side of the clutch, almost like it was done on purpose.

The rougher saw has a leak in the gas tank where the chain popped it a couple times.

These appear to have been someone's project recently, they both have new spark plugs, air filters, fuel filters and rim sprockets. The ad said nothing about the saws being Walkerized. Tomorrow I grab some 404 chain and then the true testing begins.

Let the project be rekindled. :greenchainsaw:
 
Looks like you will be having some fun, are you willing to spill the price of these 2 beasts?
 
That's some serious compression. Run the same bar and chain on both to see what the difference is in the cut one right after the other.
 
I did it on a 288xp that I had because I got tired of having so many different sizes of chain/ bars /files /sprockets etc.

Then again I have never broken a chain. Nor have a run a saw with that much Cohones before.

You can always switch back to .404 later if you want.
 
210 is insane! can't wait to see a video:popcorn:. I wonder how the piston and cylinder look on the other?

The piston/cylinder look fine viewed through the exhaust port, I am hoping a set of rings brings it back up in compression. I would think both saw were probably modifed in the same manner, they have the same Walkerized tags on the top covers.

Perhaps someone tinkered with the higher compression saw recently, but to look at the cylinder it looks identical to the other saw.
 
better send sawtroll a pm asking for bar sujestions.

personaly a saw that size i wouldnt go shorter then 36"
 
my buddy got two complete 395xps for 40 bucks. lean seized. sounds like you need a parts saw
 
Go with a 32" 3/8 with an 8 tooth. A 394 is pretty much the same class as a 066/660. The 3/8 vs .404 chain breaking myth has always baffled me, I have been running 3/8 for 15 years.
Like Brad said use good gas, your highest octane pump gas will work just fine. I build and run high compression saws all the time and have never had any issues with saws over 200psi with just 50:1 mixed 91 octane.
Good find BTW, I am getting ready to build a 395 for a guy right now. May have to put it up against my 390 when done.

You just gave me 95% of the answers to the ideas I have been tossing around in my somewhat unripened melon. Thanx man.

Both saws have .404" 7-pin rim sprockets right now, but I have no bars or chains of that size. This is a whole new arena for me, the 371 and 272 are the biggest saws I have run.

I will grab a 3/8" 32" Bar and chain as well as a 8 tooth sprocket.

How about skip chain? Semi......full.......or regular? I would want the fastest cutting set up possible as this may be more of a performance driven saw as opposed to actually bringing down the big wood.

Perhaps it's time to query some site sponsers on a sprocket, bar and chain deal.
