My '92 ford F-150 will rarely start?

It's an old truck and still needs work. My dad said that it is cold- natured. To start it you need to gas it. It will start 50 percent of the time but recently it's like 10 percent of the time. When you first try to start it you need to get it right because if you don't it wont start no matter how much you try so you have to wait a while before your next try. What needs to be done so that when you start it, it will start right away without gassing it.

Also when it does start. I have to wait for it to wind down, my dad said for the governor to kick in. Will it always be like that or can something be done so when I start it I can go immediatly.
Added (1). The battery and spark plugs are both new, spark plugs were just put in there as it came in the box, not adjusted because we didn't have the tool for it at the time, we do now tho but havent yet. When it first idles it sounds like it sputters a little until it idles down. What do you mean by misfire?
