Default Driving with choke on - what damage can occur?

Hi,
I have a carb Zen. In the morning I often has to use choke to start the car and warm it up. What the problem is - on a few occation I forgot to push the choke to its normal position and drove the car with it - though not graet distances - mostly 1 - 1.5 Km. After which I realized the mistake and corrected it.
My question is what damage can occur to the car if driven with choke on apart from fuel wastage?

No damage. Just that your car is running 'richer' and making you poorer!

Hehe... ya, and whats more, since the air-fuel mixture will be far off the stoichiometric optimal, it will create more deposits in the engine.

Come on now! He said 1.5 kms! Surely that will not adversely affect the engine in any way!

Well, he did mention "on a few ocasions", so deposits will build up. Also, even a small bit may foul your spark plug... maybe a small chance, but still a possibility! Bottomline is a vehicle should no way be driven that way.

Plug will become a bit sootier than usual, but if your engine is otherwise good condition, and you drive long stints, the soot should be burnt away.

Other than your pocket getting lighter a bit, not much harm done. Emissions are another matter, though.

Damage to your wallet will occur.
IAC if it is for a km or two after starting - this is almost the recommended procedure as you are to use the choke till engine temperature comes in to normal operating band. That said why would you need a choke start in Kolkata? Is your engine running weak compression?

Its a 2000 carb Zen - so I need to use a bit of choke to warm her up. Otherwise too much vibration and knocking in the morning.
