What causes an outboard engine to stall when giving it?
If the ratio of fuel to air becomes too high or too low, the engine will run poorly, especially while accelerating. This is because a rich fuel mixture is over-saturated with gas, causing ignition problems. Mixtures that have too much air and not enough fuel are lean and tend to reduce the amount of power available…
Can a worn out spark plug cause an engine to stall?
Old, worn out spark plugs may fail to fire, causing a misfire or even making the engine stall. Disconnect the plug wires and use a spark plug socket to remove the plugs and replace them. You may also consider replacing the spark plug wires. Be sure to reconnect the same spark plug wires to the same cylinders when done.
What causes a motorcycle engine to only run on choke?
Tiny debris particles from dirty fuel can easily block a jet, but the most common cause of clogged jets is stale fuel sitting in the carb when the bike or ATV is inactive. When fuel breaks down, it leaves behind a gummy residue, almost like a varnish that builds up on everything it touches, including the pilot and main jets.

What causes a carburetor to leak on a motorcycle?
If no changes have been made to the bike, and it previously ran well, a lean mixture can be traced to a leaking inlet manifold or leaking exhaust (often at the interface of header pipe and cylinder head).
Why are my carburetors different on my multicylinder?
On multicylinder machines, with separate carburetors for each cylinder, the following symptoms are typical of an adjustment problem: This condition is generally caused by the incorrect fitting of after-market accessories such as exhaust systems, air filter systems, or replacement carburetors of a different type or size.
What causes a carburetor to rotate on a motorcycle?
To remedy, clean your air filter, have your mechanic check the exhaust and carburetor fittings, or both. This situation is mostly caused by poor maintenance. With the inherent vibration of all engines, carburetor parts—primarily adjusting screws—tend to rotate, and therefore change their positions.
What happens when a carburetor is running too lean?
Too Lean When a carburetor is running lean, the fuel-to-air ratio is off because the carburetor is delivering too much air. Typical symptoms of a lean mixture are: Backfiring as the throttle is closed (primarily during coast-downs)
