Kia Orie idling at 2000 rpm.

The reasons for the high idle speed of the car at 2000 rpm are as follows:

Excessive idle speed of engine is caused by too soft throttle spring of carburetor, leakage of carburetor gasket, too large idle throttle hole, loose throttle shaft, poor working of individual cylinders, poor fixing of intake manifold, leakage of air valve of brake vacuum supercharger or other vacuum tubes, too small contact gap of distributor and too much carbon deposit.
