    Cold Start Issue

    Hi Friends, I'm having bit of issues when starting my car in the morning or whatever time when engine is cold. This is a Lancer CB2 with 4g15 carb engine. Have two problems actually. 1. when I crank the engine in cold it would start right away and rpm jumps to around 1300 for around 2-3 seconds and then comes back to around 300. Again the choke kicks in and rpm again goes above 1000 for a minite and again come down afterwards. Sometimes the engine stops unless I rev it for bit. RPM keeps fluctating like this until the engine gets heated up for normal operating temp. (To put it simply fast idling happens only time to time ) Once the engine heated up rpm settles around 700 and no issues afterwards. How to solve this? choke seems not working continuously. 2. Other problem is related to riding experience. I could hear engine knock when pressing on gas hard in mostly in 3rd & 4th gears. Have noticed this happens only after engine got heated up for normal operating temp and until that knocking will not occur. And I don't see any lag in pulling power nor other riding issues . What could be the reason ? Note: I'm not actually sure whether this is engine knock sound. But the sound is similar when we try to press more gas when rpm is low for that particular gear. Appreciate your valuable advices on this. Thanks.
