It starts fine at operating temp, but if it's been out in the sun and the engine compartment gets hot, it has a real hard time starting, I have to floor it and just keep the ignition engaged until it finally gets going without stalling. I've been going through the forums and it seems the fuel might be getting evaporated from the float bowl. Problem is, This is my learning car so I have no idea where the float bowl is or what I could do do fix the issue. Does this sound like it might be the problem or am I looking at a different Issue? Thanks for all the help on this!

How are the wires for the battery and all the grounds too?? This was always a problem i had as well and i swapped out everything for charging....battery,starter,solenoid, and more importantly all my ground wires.they were very bad but now i have no problem now starting up my vehicle in hot weather.
Might be that your not patting the throttle enough to get it started. Old cars don't have a computer to aid in starting the engine like the newer cars. Pat the gas a time or two before you try starting the engine. Or it could be that you need a tune-up and set the timing.
by holding his foot to the floor and cranking it hes flooding the car and forcing it to start. sounds to me the carb needs a good old fashioned cleaning and rebuilt. set the choke and a new set of points and itll most likely run like new again the old cars like these are very happy to start with just a bump of the key once warmed up as long as your carb is in good shape and is set correctly and the points are in good shape. when you first start the car in the morning or for the first time of the day you should have to only step on the gas about half way down or once to the floor for a second just to give the carb a squirt of gas and to set the choke. and wallah your car should start with just a bump of the key if all is set correctly. start by checking everything timing points and make sure the choke is working on your carb once everything is dialed in youll find your car a lot happier and even give improved gas mileage.
not trying to start anything with you here bud.. but depending on what the choke is setup for.. "holding your foot to the floor" actually leans out the A/F mixture since the throttle plates are wide open and the carb doesn't run off the boosters under cranking. A single shot off the accellerator pump and trickle of fuel from the idle circuit is all you'll get out of that deal. If you need to floor it while cranking to get it started?.. it's already flooded.
You should already have that on your car. There is a heat shield ( aluminum ) that goes under your carb ( rbs ), if that is the type carb you have. What happens is the heat from the exhaust manifold rises when you shut the engine off, and it literally boils the fuel out of the carb bowl flooding the engine. This is when you go into a store for 10 minutes or so and come back out and can't start the car. I can't take a pic of this heat shield tonight, but if you look at your carb you should see a flat aluminum plate under it that is about 4" wide x 6" long. If it is missing this is most likely your problem! There are other causes, but I have found that this heat shield is of paramount importance on a 250 during hot weather!
