Starting technique for Dellorto equipped engines (engine cold)

I found this secret :) yesterday morning and it really works on starting my engine cold. I never thought this is so simply to start a twin carburetor engine. I hope others can benefit from this too...
I got this info from http://hometown.aol.com/dvandrews/dellorto.htm

Some Dellortos have a cold start circuit (choke), others don't, in my experience, it is very easy to flood the engine and wet plugs using the cold start mechanism, as it very crude in operation. The accepted technique for cold starting is as follows:- Allow the float chambers to fill if you have an electric pump, this should take about 5-10 seconds, fully depress the accelerator rapidly four times, then on a light throttle, turn the engine over, if it does not start immediately, repeat the procedure three times. The engine should fire, but may need 'nursing' for a minute or two before it will idle, gentle prodding of the accelerator should keep it alive long enough for it to warm up. If the engine does not fire within three attempts, then try five or six pumps. If this does not work, depress the accelerator fully and hold it open while turning the engine over for 5 to 15 seconds, then close the accelerator and try again.

Project Twin Carb upgrade update 2

I left my car in the workshop yesterday for manifold installation and tuning yesterday. TK borrowed Jeya's car for me to go to work as he was not using it for the day.
Finally the manifold is been welded but it was done yesterday afternoon; Han's manage to installed it and get my car started too.
However he facing some problem during tuning on the car; I decided to pull out from the track day as I would like to get my car properly tune up and had some feel of it before I go for track.
