Jeep wont start

I just bought from a friend. I drove for three days about 30 miles around town. The headlights blinked twice then stayed on it was kind of weird. I get to house turn jeep off and turn all lights off. Next morning when I go to show my wife jeep and take her for a spin it wont start.

I have got the lights running. I changed out dimmer switch and headlight switch. Harnesses were rusty and corroded.

Now I cant get it to start. I have checked battery, fuel at tank, fuel delivery to carb, I know it cranks but wont start. Here is where I need help. Im not scared to work on my own cars I just need to know where to start on jeeps never had a jeep but I wont give up on it. I will get it to start.
