The pump or gasket could be bad. Make sure you use only bar and chain lube as this can also effect flow.

SOURCE: oil does not lube chain on my chain saw, huqvarna, any ideas

It appears from the IPL and OM this saw does not have an adjustable oiler.
OM example here (2005 - may not be your saw):
http://weborder.husqvarna.com/order_static/doc/HOUS/HOUS2005/HOUS2005_O0501001.pdf
IPL example here (2005 - may not be your saw):
http://weborder.husqvarna.com/order_static/doc/usa/2005/I05000/I0501901.pdf

I know you have done this, please verify whether or not you get the ooze with the saw running.
Oil System Plugged:

  1. 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 (oozes down side of saw). If yes reassemble your saw. If no, continue with 2.
  2. Work your way through the linkage (use IPL to identify components and locations) 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 (see IPL). I am seeing many non-adjustable oilers malfunctions, please contact Husky, there may be an unannounced repair.

If you try the repair yourself it has an outboard clutch (oiler behind it), this will help with removal. Your IPL is also beneficial.

  1. Check the IPL for your saw to see if any special tools are needed. Poulan (Craftsman, Jonsered, Husky) clutch removal tool part number 530031112 if needed, is under $5 from many sources (look at the visible area between the weights if 2 small round sockets are visible you need the tool).
  2. There are metal piston stops available, when square (almost never) with the piston top these work well, if not square they have been known to punch through the piston. I suggest a length of nylon rope (nothing left behind) be used instead of the piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises.
  3. Everyone I have ever removed had a left handed thread (tighten it to loosen it).
The OM and IPL links I provided may not be your saw. If not yours can be found here:
HusqvarnaUSA.com
http://www.husqvarna.com/us/homeowner/support/download-manuals/
Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000; black numbers on silver tag 90s; silver numbers on black tag 80s)
15 = week produced – March
00198 = 198th unit Husky produced that week

Hard starting no fuel primer noise


Hi Jack:
You don't mention make or model so all I can do is relate 50 years of personal experience.
None of the chain saws that I have owned have had a fuel primer.
This has been (and continues to be for my Husky 266) my start routine. Current saws don't have compression release.
- prep includes fill fuel and oil tanks, check chain sharp and tension, bar tip lube.
- Ignition switch on
- Choke full on
- Throttle full and lock set.
- Pull starter cord *(266 takes 3 pulls, Homelite took 6) until engine fires. If I'm fast I can get the choke off before it dies, otherwise
- Choke off, Pull starter cord. Engine should start with 1 or 2 pulls.
Hope this helps.

Chain and bar gets hot and cant saw straight


this sounds someting like the bar is worn out and now you have to tighten the chain so tight (to keep it on) that it's heating up and makiing things worse, or is auto chain lube not pumping oil up to chain ??? either way if you run long without chain lube your back to reason 1

I have a1640 partner and the oiler pump does not pump out oil when in use. I cleaned the saw and I have lost the cap which fits on the end of the plunger of the oil pump


Hi allanpriest...

Forget the auto oiler...use a handheld oil gun to lube the chain on your saw...just lube the chain approx. every 2 - 4 minutes of use
Please take time to rate me

Not enough oil to lube bar while running causing chain to over heat. When refueling the gas is empty but oil tank is over half ful yet. How may I make adjustments to solve this problem?


The machine should always run out of fuel before it runs out of oil, youhave not said what model this is, not all machines have an adjustable oil pump, some are just set for a certain length of guide bar, adusters on the oil pump increase the throw of the pump shaft so will be a slot head screw usually on the under side of the crankcase, there will also be a picture embossed into the tank with a plus and a minus, before trying to alter the pump remove the guide bar and chain and clean the the oil entry hole in the bar, and from around the bar pad.

Chain lube oil leaks when not using but not sure where from.


How do you set the chainsaw down when not using it? You're supposed to lay it on the flat side when not in use, or it will leak.

The chain oil leaks at all times model 345


There is an adjuster screw on the bottom of the saw, that has three settings. It sounds like it is turned up to high. After you adjust it to a lower setting, start the saw and then put a board in front of the bar. Rev the saw up while the chain is going and you can see lines on the board made from the oil. I usually make three lines to determine how much oil is lubing the bar. Also, lube the bar tip if you have an lube hole on your bar. The lube hole is about the size of a ink pen head. You will have to purchase a bar tip luber from your dealer. They are inexpensive and will save on bar life.

How much chan lubricant should be used and what is the grade of the oil


You want to buy Bar grade oil, it is sticky and stays on the chain, it will properly lube the bar and chain with a full tank o gas. People have used, used motor oil but this wears down the chain and gears from the micro sized filings in the oil so use clean bar oil to lube the chain correctly. also if the chain sprocket has a small hole in the tip of the saw you will need to buy a gear lube pump to keep grease in the gear at the tip of the blade. This should be lube each time you fill the fuel tank and once half way threw the tank of fuel to make the bar last longer. The bar oil is a special grade of oil and requires bar oil for it to adhere to the bar and the bar guides. Hope this helps and thanks for using fix-ya.

What is the most likely cause of oiler not working


Several causes exist. Most likely are:
1) Clogged oil-hole in bar.
2) Clogged strainer in oil tank. (part # 530056533)
3) Unhooked pickup hose in oil tank. (part # 530038373)
4) Faulty oil pump. (part # 530071259)

Of course, check oil level and use proper bar&chain lube.

Hope this helps,
