Not all Husqvarna models have an adjustable pump, if it is adjustable there will be a slot head screw either at the side of the sprocket, or just under neath the sprocket, there will be a small symbal of a drop of oil and a + and - sign.

The 50/51 and 55 always had the same bar mount, the bar was part no. 508912164 for 15" 508912172 for 18" and 508912180 for the 20", the oil is not fed through the bar adjuster hole.

Sounds like the bar is to tight.There should be a cover and 2 studs,loosen the nuts and then look for an adjusting screw at the back of the bar and back it off.The chain should have about 1/8 slack when pulled from the bottom of the bar.A tight chain will heat the bar and turn it blue close to the chain guide.A new bar will be required.

Depending on your knowledge and experience -
1. Find your manual and check on maintenance routines.
2. If no manual avail - clean your saw and your bar.
Bar - oil holes clear, groove clean etc
Saw - locate where the oil pumps out - ensure any guides, holes etc are clean.
3. If saw gas manual oil pump adjustment screw -advance the flow
4 Drain the oil tank checking for dirt etc and if necessary clean tank with a little of your fuel.
5.Refill oil tank AFTER it is clean and dry.
6. Replace bar/chain etc and test if flow is better
If still no good you may need to repair/replace oil pump -not that hard to do but if in doubt take it to a reputable dealer.

To check for proper oiling, run the saw at speed with the tip of the bar near a piece of cardboard--it should throw off a thin line of oil after several moments of running. Adjust the oil adjust screw CCW for more oil. The screw is usually in the lower front or underneath the engine. Remove the bar and chain first before adjusting anything and check the oil passages located in the drive end of the bar for plugging--especially the two small passages that go from the large oil holes out to the chain groove on both sides. Start the engine without the bar and chain--look at the oil port where the bar mounts next to the engine. It should ooze out oil with the engine running fast. If nothing at all, the pump, oil lines, and oil filter in the tank should be checked. When everything seems to be working, then adjust oil flow for best operation. Hope this helps!

turn the saw upside down, there is a little screw that only turns a quarterturn, turn it counterclockwise for the maximum flow

you can not adjust the oil pump it helps to use the right oil
