360 2 barrel skipping when cold!

I have swapped a 360 v8 in my 85 cj7.It has a remanufactured motorcraft 2150 2 barrel with electric choke.In the mornings it cranks fine,but when I take off down the road it skips,misses and runs rough, until it starts to warm up then it quits.After it warms up it runs fine.Motor just has been built,new everything. New coil,distr,wires and plugs.

Yep, thats what carbeurators do. To a certain extent, this will always happen, but you can adjust the fast idle/choke to compensate for the extra fuel needed on a cold engine. Good Luck

A stroke bolder, a pinch better.

Not so, a sound motor with a properly adjusted carb should start and run when cold. Off the top of my head, it sounds like choke problems. Check to see if it is compleatly closed when cold. It should snap when flicked open with your finger. Start the rig, does the pull off open the plate? Should be about 3/16ths of an inch(check your specs) between the horn and the plate. Is the choke idle set to specs? A low idle when cold can cause a stumble.
