Good on you for what attempted already. I looked at the print and it appears there is a worm gear (item 50) and a driven pump (item 61) behind the clutch. I suspect one of the 2 has failed. I know you have done most of this already But does it ooze with the bar off?
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).

    Sorry I am not thinking. This may be helpful with clutch removal.

    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 certain 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.

    1. Everyone I have ever removed had a left handed thread (tighten it to loosen it).

I have a McCulloch CS38EM Why is the auto oiler not producing oil to chain. The port seems to be clear.

There is a spiral ring that drives the oiler on the crankshaft. Sometimes that slips and no longer turns the oiler. You can move it back and put a few drops of thread locker on the shaft before you place the spiral in place.

The oil pump on our electric chainsaw is not working

First remove the chain and bar and inspect the oil slot that lines up with the oiler opening in the side of the engine block. You may find it plugged with impacted sawdust. Next inspect the oiler opening itself for blockage.

Oil leak mcculloch electramac em250 ?

You have a cracked tank, or busted chain oiler. Will have to take apart to view the chain oiler , and check if oil is puddling just under the oil tank. There is some epoxy sealers, or gas tank stop leak material that can possibly repair the busted or leaking oil tank.

Auto oiler

The oil filter needs to be blown out, as well as the bar and behind the bar as the feed is just an open canal on the saw side of the bar. On your model their may be a guard that needs to be removed to access where the pump assembly comes out.

Automatic oiler does not work , mcculloch em300s (electric), automatic oiler must be clogged? is there a pickup tube that can be blown out? need parts diagram to figure out if there is a pump inside.

I wasn't able to find your IPL with what you provided. Somewhere (probably bottom) should be a black and yellow tag with the serial and model numbers. The model number on that tag is the key to your IPL. If you get that far and hit a dead end with parts repost with the correct model number and your best guess at what is defective. I've had great luck finding Mac parts for my saws.
