Difficult cold start

Sounds a lot like it's not getting fuel because the choke isn't closing all the way, but also looks like you're not using correct starting procedure. That is: kick the accelerator to the floor once (twice if it's really cold or the car's been sitting a long time), then take and keep your foot away from the pedal, then crank the engine. If you've got your foot on the pedal while cranking, the choke will want to flop open. If you're sitting there pumping the accelerator, the odds are you're going to go from too lean to too rich by flooding the engine.

And for the love of Odin and Thor, once the engine starts, do not go revving it unless you like grinding parts to pieces while they're waiting for oil.
