I have had the same problem with one of my 129's the past couple of months. I have had mine outside (ran out of garage space for it) and it has been dry here, so I figured after I shut off the fuel (has a brand new petcock on it), the remaining fuel in the line dried up and left an air pocket in the line. So, it doesn't kick on until I "prime the pump" with some carb spray. My 149 sits right next to it outside,with a leaking petcock and it starts just fine.....that is why I am assuming it is the emptiness of fuel in the line. However, with the newer fuel out there.....who knows! Thanks for asking a really good question....Maybe I'm doing something wrong.
