Where is the oiler adjustment screw on stihl chainsaw 023c

MS291 Does NOT have an oil adjustment screw. It is an auto oiler. Make sure the ports are clean and oil is coming out running the saw with chain off. Then add a little canola oil to your chainsaw bar oil and thin it down. You will get a better flow. Stihl has a poor design on this model.

you cant. the oiler on an Ms230 is preset and non adjustable. Make sure the oil worm gear isnt damaged

if it doesnt have a flow screw.u dont. pull pump plate off and clean and sometimes replace pump.

Your oiler is probably defective, or perhaps it just needs the adjusting screw to be turned in a little to restrict some of the flow.

There is no oil "regulator" only an oiler with a screw that adjusts the flow, that is found below the saw, and is fit for a slotted screwdriver.

what brand saw? Stihl saws are made to run Stihl oil. If you are runnin other oil, the viscosity wont be the same as the pump is designed for, and the oiler may pump more then it should. The oil adjustment screw should be a single flat head set screw on the underside of your saw near the sprocket. Alot of saws are not equipped with an adjustable oiler. Professional saws and larger displacement saws will have the feature.

This is Stihl's manual showing the proper adjustment for the oiler. Flip the saw on its side, chain and bar side up, and look for a flat head screw.



Clockwise rotation on any saw is more oil, and counterclockwise will be less oil.

The Stihl 026 PRO does have an adjustable oiler and it is located on the bottom of the saw just below the clutch drum.
Stihl also builds an 026 "Standard" without the adjustable oiler, however, the hole location for adjustment is still there.

The 026 PRO will also have a decompression valve on top of the saw to make the rope easier to pull during startup. If you have the DECO valve you should also have the adjustable oiler. Hope this helps.
