What happens if the carburetor is not adjusted correctly?
Depending on the make and model of the vehicle, different carburetors may have multiple, sometimes up to four, air fuel mixture adjustment screws. These screws are responsible for controlling the amount of fuel that enters the engine, and improper adjustment will result in decreased engine performance.

Cleaning a carburetor without removing it is fine. However, it can and should never replace the wholesome cleaning exercises. This is because it does not impact the entire length and breadth of the engine as should be the case.
Is it important to have a constant idle speed?

What should idle speed be on nastyz28 Edelbrock?
So adjusted the idle speed screw to 700rpm no problem. Then adjusted the mixture screw (right to max rpm according to instructions) well it got right back up to 900 again after a few turns and I’m concerned the screw is going to pop out of the carb so I stopped. Then I adjusted Idle screw again so its at 700rpm again.
What causes a choke to stay on fast idle too long?
Stays on fast idle too long: The choke spring tension is too tight, the heat source is not being supplied or is blocked, or the fast-idle cam is gummed up, bent or has another problem that does not allow it to drop.
How can I keep my car from stalling on cold start?
You’d set the idle speed set screw to your desired idle speed with the engine warm, and if your on/off valve is big enough, turning it on will keep the engine from stalling on a cold start. No closed loop control is possible.
