Why does my carburetor not work when I start the car?
Why does my carburetor not work when I start the car?
There are numerous variables. Cold-starting and warm-up require a richer mixture, which is usually handled by a choke butterfly that limits the amount of air into the carburetor until the engine is at operating temperature. Acceleration, heavy loads and, in some cases, idling also require a richer mixture.
Why does my no crank no start car not start?
Inside the relay, a set of electrical contacts allows current to flow to the starter solenoid. If these contacts become corroded or extremely worn, they may not get the job done. An external starter solenoid, unlike the relay, carries high voltages.
Is the choke spring part of the carburetor?
Spring: The choke spring can be either integral (a part of the carburetor), such as the design used on the later Rochester Quadrajet, or divorced (not attached to the carburetor), which was common on Chrysler products. When divorced, a linkage connects the spring to the choke plate.
What happens when a carburetor is stuck in the cold position?
If this valve is stuck in the cold position, it will constantly direct hot exhaust gasses under the carburetor. This can cause hard starting when hot, as the fuel will have boiled out of the float bowl.
What are the symptoms of a carburetion problem?
Symptoms of a rich mixture can be misfiring and stalling at idle. Copious amounts of black smoke from the exhaust pipe are a tip-off to this condition.
What’s the idle speed of a 1988 Camaro?
When in gear (ex. Reverse, Drive, 2nd, 1st) my car idle “settles” around 750 on the tach, but then starts to fluctuate around there, moving up to 900 (or so) then dips down to about 500 on the tach. While the idle speed is fluctuating my voltage drops dramatically.
What to do if your Camaro has a bad idle?
Take a real good look at the throttle “butterfly” valve. They have a tendency to get buildup with dirt and will stick slightly open, confusing the computer into thinking that you are pushing on the “go” pedal. Get some carb cleaner, or even better, GM Top Engine cleaner, and really clean out the throttle valve and air intake area.
What should I do if my carburetor is not working?
If the engine is not running right, the carburetor is the last thing that should be checked before blindly tearing into it. Ensure that compression is up to par in all of the cylinders, the valves are adjusted to their set clearances and the ignition system is operating properly.
Where is the idle air control valve on a Camaro?
I’m going to say check your IAC valve (idle air control), this is located on the passenger side underneath the throttle body. These get all carboned up and can’t re-seat themselves properly. You may have to perform a minimum idle setting also.
