I am back. I couldn't wait for next thursday so last wednesday I called into another mower shop and asked if they had an old carby. As soon as he heard it was a Talon he had a pained expression and said,"They're not much good". Anyway he sold me a used carby for $20 and if I wanted the fuel tank it would be extra. I took it home and swapped them over. It ran like a demon on the third pull...FIXED!!
I got curious as to why the old carby wouldn't work so I pulled both apart. The words of Grumpy soon came to mind "but be careful as there is a small brass jet that can easily be dislodged and lost". Somewhere in my garage it lies, undisturbed, mocking me forever.
Thank you to all who helped.
