It's almost definately your choke is set too rich.  Or like mine it's
"choking cycle" is not consistent with the engine warming rate.  My
1985 Ford 5.8 liter engine has a choke which is too rich when I start
it and after I drive a mile or so it is too lean.
A good verification of too rich of choke is when it is shaking, look
at the exhaust gasses.  It will be thick black smoke and smelly.  And
also your spark plugs will be fouled as a result....

As previously discussed, the new chokes are "non-adjustable" but if it
really is your problem, the mechanics can grind off the rivits and
easily adjust it.
