Had it with automatic choke

I recently installed a rebuilt Motorcraft 2-barrel carb on my 1985 Econoline. I cannot get the choke to work properly no matter what adjustments I make. It starts fine, but after a few minutes it starts spitting and sputtering like it's going to die, and it does if I don't work the pedal. This will go on for 10 minutes or so until the engine finally warms up. I'm tired of dealing with it. Can I install a manual choke and eliminate this automatic piece of crap?

For your make and model im not sure how its done but I do not see any reason why it cant be done or that it would hurt anything.
