88 accord DX, M/T, 221k, carb. Great engine rough starts. I observe the plate when it starts cold and it seem that the plate doesn't open up fast enough (i open it fully with my finger and all the shaking stops). The engine shakes, while it seemed to be burning rich (gray-light black smoke coming out tail pipe); especially cold days. It idles opposite of what it should be when starting cold - I have to give it some gas to keep it warm up and it idles high (can go up between 2k-3k rmp) when it half-way warm. A tap on the accel. Pedal brings it down to normal idle

It idles fine after warmed up. An auto part person told me its running rich, is that right!

Sounds rich but you haven't described too much about how it runs once the car is warm. If the car only has problems when cold I would suspect that the choke is the problem and a sensor. Not real experienced on carbed Honda to know whether they are mechanically detecting engine heat or electronically sensing the heat or lack there of. To me your choke and carb are the issue.

Check the EACV and the fast idle valve
