Look-up the UT-43103 IPL. There is no provision to adjust the oil flow. Suggest checking the oil lines for loose or broken areas; also could replace the oil pump. These are very inexpensive parts. here is a link to the parts list and source for the parts.

The Husqvarna 240 does not have an adjustable oiler. Always use good quality bar and chain lube, never motor oil.

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.

The pump is not adjustable, it is very unusual for them to over oil, the pump shaft can only rotate at the speed of the engine, it is calibrated to cope with a 15" bar, it is more likley it is leaking out of the oil tank.

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.

I would just pre mix 50:1 in fuel can and skip the auto mix.

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.

There is a pumped volume adjustment screw located near the rear case bottom and the lower part of the chain. Turn CCW somewhat to increase volume. Be sure to clean the bar oil passages including the two small channels that run from the large holes out to the chain groove on each side. Clean the entire groove. When everything is back together, run the saw at speed with the bar tip near a piece of cardboard--it should throw off a thin line of oil after several moments. Hope this helps!

That seems low to me. Page 15 in your manual is the only oil discussion I found. Usually there is an oil pump adjustment reference somewhere. I didn't see one beyond return it for service on page 15. Are the chain and bar hot after cutting a while? I recommend you not get a longer bar without an oiler adjustment. I think the hand of the EPA has been here.

Might be a good idea to copy the IPL,
