how to start carbureted engine
Does cold weather affect carburetor?
Cold air is denser than warm air, which means even a properly tuned carburetor may struggle with a too-lean mixture on a cold morning as it pulls in the same volume of air, but more tightly packed, increasing the air-to-fuel ratio.20-Feb-2018
How do you adjust the carburetor on cold weather?
You shouldn't need to "tune" the carburetor for cold conditions. That's what the choke system is for. On a "cold" morning before you've started the engine, get in the car and quickly depress the throttle pedal. That will reset the choke.27-Dec-2009

Why are carbureted engines hard to start in the cold?
From Wikipedia: When the engine is cold, fuel vaporizes less readily and tends to condense on the walls of the intake manifold, starving the cylinders of fuel and making the engine difficult to start; thus, a richer mixture (more fuel to air) is required to start and run the engine until it warms up.30-Sept-2019

Do carbureted engines need to warm up?
Cars with electronic fuel injection do not need to be warmed up before lightly driving off. This is because fuel injected engines can compensate for temperature changes. Cold engines run rich to compensate for poor fuel atomization. This means extra fuel is injected into the combustion chamber.
How long should I let my engine warm up?
When temperatures drop during winter it's a good idea to let the car run for about a minute. Some drivers prefer to let the engine idle for 20 minutes or longer to get everything—including the cabin—really warm, but the fastest way to warm up an engine is by driving.26-Dec-2021
How long should you warm up a carbureted engine?
Allow engine to fast idle for 2-3 minutes or so. During the warm up, DO NOT TAP THROTTLE TO DROP FAST IDLE.
