I have blown the oiler port out with air and cleaned any debris from oiler port, someone suggested running petrol throgh it which I did seemed to come out more but as soon as I added the chain oil it only used about one fifth of the oil to a full tank of petrol? So I am stuck the unit looks like it is sealed inside the oil tank so no idea onto go further with a repair

Re: Ryobi 40cc chain saw oiler not working correctly
Hi Check and clean the oil filter from oil tank.Check the worm gear wich engages with the oil piston pump(under the clutch).Near the hole where the oil comes out from oil tank there is an oil tank valve(see if it is clogged),it equalises the presure between interior and exterior of the oil tank. best reagards savumihai71
Re: Ryobi 40cc chain saw oiler not working correctly
You have done what I would have done and have done successfully in the past. If the chain is not sticking or seizing on the bar than you may be O.K. - many saws still have a portion of their chain oil left when the gas tank has run dry. If the chain is not seizing then run the saw in a safe manner with a fairly large piece of clean cardboard under the saw. As you rev the saw moderately look and see if there is any oil being thrown onto the cardboard - if so you may be fine.
If the chain does seize than you may try the petrol/gas mix method again and this time dump the petrol after a few seconds into a container - hopefully this may dislodge any debris that may have gotten into the oil resevoir. You''ll have had to empty the oil resevoir of oil before you try this and lossen the chain with the adjustment provisions of your saw. As a side note, I can say that prolonged running of petrol through the oil pum may damage it.
A final thought - is the weather you are working in extremely cold and if so are you using summer/heavy grade chain oil. This combination may cause or contribute to a lube problem. If I'm correct in this assumption then swiching to winter grade chain lube may work. For a tank or so you could try a 5-30 weight motor oil for a chain lube - don't use it for gas mix though!
Should these suggestions fail a visit to the chain saw shop may be in order as pulling apart the oil tank usually involves dismantling a large portion of the saw.

wow this seems to be a more frequent complaint with folks bringing me there saws to look at lately , what I almost always find wrong is debris in the oil tank hence it's in the oil pump too , this requires a total take apart and clean it out service , also folks seem to not know what oil goes in there and add just any kind they have (even 2cyc oil) me I like to say u use Bar chain oil , this most times is 30w or less if it gets any heavier or lighter the oil pump M/T's the oil tank out first before the fuel tank goes M/T , oiler is not adjusted correct if your not needing to add oil with every gas tank fill
I get asked this question a lot , im gonna have to make a video on this subject someday .
1st ck your oil viscosity/SAE it should be 30 and say bar/chain oil
next dump out entire oil tank and wash out with kerosene (you'd be surprised what I seen come out)
then remove bar and chain , locate oil outlet it's in body of saw near adjustment screw , use a small can of air to blow in this port softly , use a touch more of kero to clean this all out , refill tank with proper oil !!!! and run saw (no need to put bar/chain back on yet ) might take several minutes but oil should start to flow out hole !! stop saw and reinstall bar/chain then run again .. fixed !! if no oil comes out ever your oil pump is gonna need some fixing
for a low cost oil I use filtered used motor oil cut down with a dab of kerosene
Take your saw or old chain to a shop that works on small motors and they can make one . Take it to lowes and try one of theirs. They have them to fit any brand saw. Sears, Home Depot or a small hardware store.
Had you provided the model number we could have provided a more complete answer. What little oil system routing detial there is resides on the IPL. It can be found here: Homelite/Ryobi.com https://www.gardnerinc.com/recons/disclaimer-lg.php - Agree; Choose “Product Line”; “Select OEM” & “Select Catalog” both to “Homelite Consumer Products”. A drop down list appears; self explanatory from here. The numbers Homelite & Ryobi use don't match the numbers everyone posts. A careful inspection of your saw should find something that matches.
Oil System Plugged. Remove the clutch cover, bar and chain. Clean the oiler hole and channel. Start the saw and see if it oils when revved up. If yes reassemble your saw. If no a blunted, hooked piece of wire can be used to pull the hose in the oil tank out. I recommend the filter be replaced. Work your way through the linkage cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at connections. If equipped with an oil pump it is usually behind the clutch (probably left handed thread). Please make extensive notes & some digital pictures will help during reassembly. GL Lou
