395 tuning

[Dustin4185]

I have finally ran four tanks of 32:1 red armor through my 395. This thing is running way rich. I bought the splines carb tool to adjust it. My tach says 9,500 out of the wood. I was able to adjust to 10,100 with the screwdriver. What should I set this saw at? It is still four stroking at 12,500 and doesn't really clean up in the cut. This saw wears a 32" usually with a 42" occasionaly.

Is it stock or ported?

Try 13,200 and go from there. Gotta remember that saw has a lot of rotating mass, can't spin it too fast

Stock....for now.

What is the best way to set the limiters so I can use a screwdriver to fine tune in the woods? I didn't try it after adjusting to 12,500 with the spline tool. Does it max the screwdriver screw or does it maintain a middle type adjustment? This is the first carb I've had with the spline limiters. Sorry for being dumb!

The factory recommended rpm is for the break in period and is meant to be richer. After break in, it is recommended to tune by ear. Maybe keep the spline tool on hand for fine tuning at elevation.

First, I disable jet limiter screws if I can, I despise the damn things. If the spline tool is handy, don't put the limiters on and keep the tool in your saw box for fine tuning as needed.

Second, keep tuning till it cleans up in the cut and readily 4-strokes if you lift in the cut. Remember, if working the saw hard on a long cut in big hardwood on a hot day, heat soak will lean you out a bit from your primary setting. What seems to be a good setting with a couple quick cuts can be a bit too lean when you really work the saw and she starts making real heat.

Third, I wouldn't get hung up on a target RPM number. Tune the saw to what it is asking for. If it isn't cleaning up in the cut in a timely manner, 12,500 isn't enough yet. But if you want to run a bit of a safety margin, leave her a little rich. Nothing wrong with that. Otherwise tune it as I suggested above.

Tune it safe for long cuts.

12,500 is fine... especially if it wears a 42". Id think 12-12.5 is where I personally would run it....and I have 2 394s.

Thanks to all that responded. Part of the reason I brought this up is because I had to go by the dealer I purchased it at (farmers CoOp) to pick up some 026 parts and some stuff for work. I took it with me to have the small engine guy retune. He said it was tuned good. I told him it still four strokes in the wood and I have ran a few tanks through it. He told me it should always four stroke. I just got my stuff and left. I will talk to the other technician next week. He seems to know more and actually used to be a logger until he broke his back. He is the one that sold me the spline tool last week. I think I will stay around 12,000-12,500 to be safe for now. It will be going to Randy soon.

Nothing wrong with playing it safe.

I'm sure the pistol wielding primate will take good care of you.

Take a file swipe or two off the rakers if it won't clean up in the wood without pressure.

I have it dialed in now.
