This is the cold start procedure for my FB RX-7, the video ends when the engine is warm enough to hold idle (aka, warm enough to drive); however, the engine is still cold and will have to be short shifted below 3 thousand rpm until it reaches operating temperature.
For those who care, the procedure on paper is something like this:
1. turn key to the “on” position – this starts the fuel pump and primes the carburetor with enough fuel to start the car.
2. pull the choke – while the fuel pump is priming, pull the choke so that the engine will start easily; the choke system will use magnets to hold the choke out if the key is in the “on” position.
3. crank the motor – depending on ambient temperature, and how long the car sat since the last start, you may have to wait quite a while for the fuel pump to prime before it will start; on warm days, you can crank the motor pretty much immediately, but on cold days it may take nearly a minute for the fuel system to prime.
4. watch rpm and adjust choke position – rpm shouldn’t exceed 2500 right after starting, and higher rpm will consume more fuel; I usually adjust it to about 1500rpm after its running
5. wait – the motor needs some time to warm up and smooth out.
6. test idle speed – push the choke in and see if it will maintain idle speed, if not, pull the choke back and wait a bit longer.
7. drive off – once the motor will hold idle, it is warm enough to begin driving. It will warm up to operating temperature faster by driving than sitting with the choke out; it is also more economical to use the fuel to get somewhere, but remember to short shift (shift early, below 3 thousand rpm), and double clutch the transmission if its making a fuss about gear changes. NO REV UNTIL WARM.
