Chainsaw adjustment

Some time back there was a good thread on adjusting a chainsaw carb. I did not print it out and now need the info but cannot find it. Can someone bring it back up or give me instructions. I have tried to do a search but my webtv does not let me get into the archives. Thanks, Tom

I have a Stihl and haven't touched the carb in ten years other than clean it out occasionally after heavy use.
ATTACH A LENGTH OF CHAIN TO IT AND SELL THE POULAN AT YOUR NEXT YARD SALE AS A BOAT ANCHOR.
Pack slow, fall stable, pull high, hit dead center.

Regarding the adjustment: First gently screw in both the high and the low speed MIXTURE screws till they seat. Don't get ham * here. You can dammage things. DON'T mess with the idle adjustment screw. It rarely needs any adjusting. Next, back out both screws aproximately 1 1/8 turns. Start the saw and adjust the LOW speed screw in or out (very small increments) to get a good idle (no chain creep) and a clean, smooth acceleration when the throttle trigger is pulled. Next, wind her up and tweak the HIGH speed so that it blubbers a little bit at the top end. If you have it screaming flat out you are WAY TOO LEAN. If in doubt, err to the rich side, ie; open the HIGH speed needle a little more. Ideally you would have a tach to set the top end but they are not always available. If this doesn't work I suggest you take it to a repair shop and see if they can help you. I used to check RPMs for people for free as a PR gesture. I have Stihl digital tach that is great for this but a bit spendy for the average home owner.
Try this site.. at the bottom it has poulin.. myself I find the stihl and jonsered the best
Yes guys, I know how to operate them.. operate a skidder as well..

And now I get it, the motor is supposed to run!
I'll admit it does saw better now with the chain moving, but it sure is noisier than before.
The URL you provided is outstanding. I never heard of "HowStuffWorks" before - I bookmarked that one most carefully. Thanks!!
BRoses, thanks for the site. I will check it out later. PS My g/f runs my dozer and she loves it!Roysha, your replywas what I was looking for. That darn idle screw was what was killing me. I usually don't have much trouble adusting these things but this one was giving me fits. Chainsaws are like cars, you can buy a Chevy or Caddy and both will probably get the job done. I like Poulans because I used to live in Louisiana and they are made in Shreveport. I like to spend my money where I live. Poulans have served me well and I have never worn one out. They do get more abuse from sitting than from running. Thanks to all. Tom

If you don't care where you are going, you can't get lost.
NEVER...adjust a carb unless the air filter is cleaned PROPERLY FIRST!
It will change the air/fuel, giving a false-less than optium setting.
Many a cylinder/piston has been ruined running the saw lean when carbs were cleaned AFTER the adjustments were made.
USE...ONLY a small, short screwdriver. You are GENTLY turning a pointed steel(hard) screw into a zinc alloy (soft)body. Once it's damaged, it's ruined. Forever.
Do suggest that you turn the Idle screw out, then in till it touches the cam plate. Then 1 turn IN. The chain may creep-run when started, but that's ok for the moment. Be Careful.
Once the LO side screw has been adjusted, THEN turn the Idle screw out till the chain stops turning. If it's too low, the saw will bog-stumble, or die. Final testing will happen after the next step.
Follow the earlier instructions on the Hi side screw. Pay attention to what he said!!!!! Screaming isn't power.
Poulan builds saws for Husky, and Jonsered. The new Stihls, Husky, and Jonsereds are being built like Poulans design. They all are going chaeper for the volume market.
Personally would take a big Husky, Jonsered, or better yet a DOLMAR (world's First chain saw) over a Stihl,....if the Dealer was there to support the line. Less vibration, simpler design, and equal if not more power.
Happy Bullet Holes!
its a hacksaw frame with 12" of dog chain in it.
sorta slow mover.
