When you prime it, can you see fuel spraying into the idle hole in the front of the motor? (Is it getting any fuel to the idle circuit?)

I tried that this morning, and I could see a mist of fuel coming out of the hole. So it worked. Then the plot thickened.
For good measure I removed the low speed needle from the engine, cleaned it, blew out the hole with compressed air, and remounted it. Now the primer pump will not work anymore. It builds up pressure, I need to press it harder than earlier when it worked, but there is no longer fuel coming out of the hole. So there definitely seems to be a blockage somewhere, or I have made a mistake when remounting the low speed needle.
So right now my money is on the low speed fuel line (as several of you suggested). Especially since the compression seems to be ok. I’ll get back to it later today and keep you posted.
