Tiger, if you where located in Brisbane I would invite you round and we could both fix your mower and have a yarn.
Place a piece of pipe on the valve as below.

Then suck on the hose, the valve should close, see closed valve below.

I use a clean pipe for this, I dont put petrol in my mouth.
I certainly wouldnt tell you how to feel or act, but I try not to let a mower defeat me, it is just a hunk of metal.
When I hit a dead end, I put it aside and come back to it later.
