1. Lean Air/Fuel Mixture. Not only can a rich air/fuel ratio cause a backfire, a mixture that doesn’t have enough gasoline can cause a backfire, too. A “lean” mixture is one that doesn’t have enough fuel, and too much air.
Why does my carburetor hesitation?
Adjust the idle. Using a vacuum gauge and setting for the highest vacuum can cause hesitation (see the paragraph on BOG). … The mixture delivered by the carburetor is controlled by the idle tubes (gasoline jets), and the idle air bleeds (air jets) in the carburetor.
Can spark plugs cause hesitation?
If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle. … The weakened spark produces poor combustion which can lead to performance issues including poor acceleration, hesitation and rough starts.
What causes jerking during acceleration?
