20 Most Recent Husqvarna "Chain Saw - 16" Bar, 3 Hp - Page 2 Questions & Answers

Adjust the Low idle screw so that it doesn't die out. On most saws, to adjust the idle, look for an opening that has an L next to it (there is also one for high idle speed with an H next to it). Use a small screwdriver, and be careful--many of the idle adjustment screws are plastic so you don't want to strip it.

Have you checked the throttle is returning to tickover on the carb ? cable sticking ? If it is on tickover and still high reving then you could have an air leak after the carb , check the intake manifold , crank seals could be worn and this will let the engine rev by its self ! fuel mixture correct as if its 2stroke a lean mix can do this as well ! ??

Replace the fuel filter in the tank, check the fuel hose up to the carb for signs of leaking, if so replace the line, between the cylinder and the carb back plate is a rubber induction tube, make sure this has no split.

May need to replace the oiler. I would also take the bar off and make sure the little hole in the bar that allows the oil into the grooves isn't clogged!

More information is needed... it could be just a number in the molding. What are you trying to accomplish

It sounds as though it is lean. Operating it lean may cause failure. This may be caused by many things including but not limited to; leaky intake connections at the engine or carburetor; leaky crankcase seals; cracked fuel delivery lines.
If no air leaks tweaking the carburetor may solve it but be warned; frequent carburetor adjustment can mask a much more serious problem. Try turning the "L" needle CCW (richer a little). This is the best adjustment procedure I have found.

• CW is leaner; to lean will destroy the saw. If over tightened closed (CW) the adjustment screw faces are easily marred; marred adjustments are difficult to impossible to set properly.
• Clean the air filter; adjusting with a dirty filter can cause a run lean condition once cleaned and the saw run.
• Clean the spark arrestor and muffler; if the saw cannot exhale it cannot inhale.
• There are 2 wav (sound - idle & full - may not be highlighted) files that I find most helpful, I think you will too.

There is no problem as long as the bar is the right bar and the new chain you use is the right pitch for the sprocket that is on your saw.

No big deal every one has done it. Plus it will give it a bit of a clean for you. Just tip it out there is not a lot that goes wrong I that area.

All adjustments made to the fuel are screw adjusted, three screws are low ideal, high ideal, throttle stop. A flat he'd screw driver should do.

You removed the cover while the chain brake was in the locked position.  The plier method will be a pain in the ***, as you cannot get enough leverage to twist lock or spread the spring.   I've accidently done this myself and found a much easier way to solve the problem.  Just remove the chain brake handle by unscrewing 2 screws.  Stick the cover and the handle together as they would if it was correctly assembled and twist.  You should be able to unlock the chain brake and it will now slide right on.

tilt engine and remove all bolts that hold gearbox to leg , put box in vice and remove impellor house and remove impellor , check all holes and seals below housing for damage etc , if impellor has broken up then check water down pipe is clear , you can run engine with box off and put hose to down pipe and turn water on and run engine for 20min and see if engine cools b4 you fit box so you know no blockages etc ! as you fit impellor rotate clockwise as you push down on housing , bolt up and fit box and as you do turn flywheel to engauge driveshaft ! Bobs your uncle ....

90% sure it's 5/32

I would find a lawn and garden shop that repairs chainsaws. Take your saw there and they should be able to get you the correct file.

when ??? dies at wide open throttle ??? dies at idle ??? dies it restart right away or take an hour or more ??? did you put the right 2 cycle mix in the gas tank ???
