Classic/Antique Car Repair: F-600 Ford holly 1967, gasoline smell, ford club

Question
I am facing a problem with my car , when I start it it runs but it gives a gasoline
smell and running is not normal.
kindly help to find out what is the reason, with thanks

Answer
I am a Model A guy, and I don't know anything about your truck except it sounds like it is running way too rich.  This will fowl the plugs if you run it very long in this state.  See if the choke is stuct closed.  That was a common problem back then.  Join a Ford club and get help from them.
