Can anybody explain, how works the cold start on Rochester 4 barrel. Seams is not working on my car.
1) Push the gas peddle all the way to the floor once and let it back up (this primes the engine, closes the choke as much as needed and sets the fast idle linkage.
2) crank the engine with your foot off the gas pedal. When the engine starts the vacuum operated choke pull off will open the choke enough so the engine will keep running.
3) The fast idle linkage will release once the choke is fully open while you're driving or if you just tap the gas pedal after the engine warms up.
