Is it normal for a carburetor to hard start?
The hard starting just doesn’t seem right after sitting for only a couple of days in the garage. Thanks for the help. That isn’t a problem. It is normal. The gas evaporates from the carb, and you need to crank the engine long enough to get fuel from the gas tank which is about 15 feet away from the engine and below it.
What should I do if my carburetor is stalling?
Then, back off on your idle set screw to lower your idle while continuing to spray into the carburetor. Keep backing off the screw until it is no longer contacting the throttle linkage. By doing this, you are taking away air and your car should stall, or at least idle down very low to 600 RPM or lower.
Can a carburetor be turned all the way in?
If it is too rich the best idle will be achieved with the mixture screw turned all the way in (never torque a mixture screw tight, only lightly screw it in to find the seat). If your idle is still rough with the mixture screw turned in and it’s not lean you will likely need to rebuild your carburetor.

What to do if your carburetor is not working?
A problem with the float is also likely to cause flooding when trying to start the engine. Check the adjustment on your float pin, and maybe even get a new one, and this should hopefully stop your problem!
Why does my car not start when idle?
Low engine compression caused by worn piston rings, cylinders and leaking valves. Faulty coolant and/or air temperature sensors gives your engine computer incorrect information resulting in improper air/fuel mixture.
When to start and run a carburetor needle?
June 20, 2015 at 6:27 pm The engine should start and run at any setting between 1 and 1 1/2 turns out from finger tight. Make sure the needle and seat are both clean before installing the needle, BUT be CAREFUL not to damage either by cleaning with metal (wire). After the engine warms up the idle can be fine tuned for optimal performance.
