My thoughts:
1. Does the new fuel line from the pump to the carb have a section of rubber in it? If so it may become pliable from engine heat and collapse on itself. Once the fuel is flowing again it will stiffen back up and be fine, but the initial start up will be bothersome.
2. The vacuum baffle in the air cleaner intake pipe. May be stuck closed and not getting enough vacuum to open until engine rpms are raised.
3. Carb choke. sticking closed when metal expands from heat, the rod may not move freely in the guide hole.
4. Hot air choke tube?
5. Timing too advanced? I'd check it just in case.

Try taking off the air cleaner lid, propping the choke open with a screwdriver,and pumping the gas pedal 10 times. It should start on 1 crank.
