So I just recently installed a new carburetor on my 1965 Mustang coup 289 v8 because my old one broke and started leaking when I rebuilt it. I haven’t touched the lines since I last replaced the spark plugs and since then I’ve driven it three times. My carburetor gets fuel but it won’t start. I have to put fuel in the intake valves and then rev it up really height before it will run on its own. My carburetors choke valve is also unresponsive to my gas pedal. Please help
