Oil problem Ms 261c

Hi guys, So I recently had an MS261C in for service. I changed what I needed to change, membranes, spark plug and all the stuff…

And when I restarted the machine, I noticed that the oil was no longer coming out of the guide.

I then did everything : cleaning the oil tank, changing the oil pump (it was no longer pumping), cleaning the oil pipe to the guide, cleaning the tank-pump pipe, putting new guide on and even a new chain... But nothing to do, the oil is not coming out... The pump has been tested (unplugged) 3 times (it is new and works perfectly) and the pipes are unclogged, the pump adjustment screw is set to "max opening".

So here I am, asking for a little help because I am completely stuck there…
