I smell like gas after driving!

That is not normal and demands attention.
I am assuming you're talking raw gas smell. You are gonna have to hunt it down, starting with external leaks. I have experienced this with vapors coming in through the cowl. You go look for it and you will find it. .You have to.
Is the factory cowl seal in place at the back underside of the hood?
Do you have the stock air filter house on the carb?
Is the carbon-canister hooked up and functioning?
Check the entire supply line systems but especially the hi-pressure section from the pump to the carb.
Are there other driveability issues?
