Default 1985 4.9 won't start when cold

My 1985 F150 with 4.9L won't start when cold. I can spray starter fluid into the 1bbl carb and it will start and run fine. I replaced the mechanical fuel pump this summer and it did not help. Any ideas?

Check the operation of the choke flap, bi-metal stat and pull off diaphram.Also, make sure the carb is snug on the manifold.
