I assume you are referring to an AD Chummy, I recently had issues with an AE Chummy hood for similar reasons to those you describe, these do sit somewhat awkwardly even when straight. I also have an AD Chummy which is dismantled at present there is a fairly straight hood frame I can measure for you, could you please photograph the areas you are concerned about.
