Experienced gardeners share their insights in answering this question :
Oil System Plugged.

Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar), if equipped with a sprocket nose ensure it rotates easily at least one complete revolution. Clean the saw oiler hole and channel. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out. Pay attention to the screen or filter on the free end (clean or replace, difficult to determine serviceability). Start the saw and see if it oils when revved up. If yes reassemble your saw. If no, continue with 2.
Work your way through the linkage cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is a left handed thread). Please make extensive notes & some digital pictures will help during reassembly.
If it does not oil on completion of 1 it is most likely a bad oiler or worm gear. Post back with a model and serial number plus what you have done, we will help you with repair/replacement. HTH

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

Some chain saws with automatic oilers have a screw you can turn clockwise to increase the flow of oil. Turn the screw clockwise, and retest your saw`s lubrication by running it while holding it above a light colored surface to see if you notice a mist of oil.
There is a Debris Obstruction in the Oiling System. Occasionally saw dust can get in the system and clog one of the various conduits the oil needs to flow through. This is one of the most common reasons for a bar and chain not getting oil, and it is fairly simple to fix.
Naturally, the chain of your chainsaw will need to be oiled well to function perfectly. To make sure that it functions well, grab some WD-40 Multi-Use-Product. WD-40 works great for both – rust prevention and lubrication.
Lubricate the chainsaw

When you put the chain back onto your chainsaw, you will have to lubricate it to clean it, using WD-40® Multi-Use Product. Before refitting the chain into the chainsaw, wipe off all the excess residue and then reattach it to the guide bar.

One tell-tale sign that a chainsaw has flooded is the smell of fresh petrol near the muffler. To ascertain whether this is indeed the problem, simply disassemble the part, pull the starter cord as if you were switching on the engine, then dry it, reassemble it and try switching it on again.
The most common reasons why your automatic oiler isn`t working are: Your chainsaw`s oil tank is empty. The chainsaw oiler is clogged. The oil pump is broken.
It`s important to note that oil tanks cannot simply vent into the atmosphere, as this could lead to the oil leaking onto the operator during use. To avoid your chainsaw from leaking oil whist in storage, the best solution is to drain the chainsaw of its bar oil and fuel mix and store the chainsaw empty.

The automatic chain oiler does not get oil to the chain. Yes, it has chain oil. The black tube to the top chamber at the bar, seems to be plugged and I cant get it off to clean it out. Thanks, Steve
ANSWER : I have never seen an automatic chain oiler that worked. Even new ones don’t seem to work. Just pour a little used engine oil on the bar once in awhile like everyone else does.In theory there is a small piston that rubs on an eccentric at the chain sprocket, and that sucks in oil and pushes it through a hole, into the center groove of the bar.But if the piston is dry, it won’t pump.If the holes are clogged with sawdust, it won’t work.Here is a video that may help:http://www.ehow.com/video_4756894_a-chain-saw-bar-oiler.html
