Thanks for the interesting discussion here. I had a similar problem and followed this disassembly: as I found out that mud wasps or something had filled the transfer tube (and some of the rest of the fuel line) with mud/silt which was blocking the fuel flow. After partial disassembly, I used a stiff wire to ream it out, ran some hot water through it, scraped some more mud out, and reassembled and it worked. Sometimes the most obvious solution is the answer -- something was blocking the tube i.e. mud.
Old thread, but in the years that passed when this thread was live I got rid of all my 425’s. I now have only 413s and a 426. It is obviously all @snwcmpr ’s fault. Brad
