Sounds like you're not getting the vacuum that's needed to open the petcock in "run" & "reserve" ("prime" doesn't need a vacuum) Check the vacuum pipe that goes from the engine to the petcock for splits & tightness.
Thank you alantf-

I checked the hose and it looks fine. Is there another vacume hose? I read in a different post on a similare problem and someone mentioned an "S" hose form the crank case to the filter box? I havnt checked it yet but when I do I will, could that be affecting it too?

Thank you all again for your help. I hate that I am having all these questions and answers without any resolution, but I know I will be able to look back on this and be thankful for the learning experince
And then it will be your turn to impart wisdom and experience to the next new member. For a smaller forum this one is just chalk full of info and helpful folks.
