Question

hello friends,
when a motor cycle engine flooded and what kind of problem arises if an engine flooded?how to solve the problem and what precautions we need to take to overcome it?

Answer 1

Depends on the engine type.
A 4 stroke can become hydro locked.
Cylinder filled with fuel above the piston.
If both valves are closed and the piston moves up on the compression stroke, so much fuel won't be able to be compressed and the engine can bend a connecting rod.
Personal experience.
A 2 stroke will over fill the bottom end of the crankcase.
There's to much fuel to be transferred to the combustion chamber.
Part of it is transferred and drowns out the spark plug, preventing it from firing.
Then more fuel is sucked into the bottom end making it over filled and the process repeats.
Fill the crankcase - transfer part of it - drown out the spark plug - fill the crankcase again - repeat.
To de-flood an engine, remove the spark plugs and crank the engine.
The compression will blow the excess fuel out of the spark plug hole.
To prevent the problem - make sure the carbs aren't overfilling due to incorrect float height, stuck floats, or worn float needle & seats.

Answer 2

I'm assuming the bike is carbureted.
Fuel flooding, (fuel overflowing from carb into cylinder(s) is usually caused by a stuck-open carb float (in the float bowl under the carb), a sunken float (float no longer floats-holding the needle valve open), or some debris not alowing the float needle valve to close completely when the bowl is full.

The cure involves removing the carb (you'll need to turn it upside down) and removing the float bowl and disassembling the float and needle and cleaning the needle and needle valve seat. Sounds hard but is pretty easy.

Flooding causes not only poor performance and poor fuel economy, but it also fouls the spark plugs and exhaust and under extreme conditions causes a condition known as "washdown" wherein the fuel actually "washes" the lubricating oil off of the cylinder bores leading to sealing ring damage or worse-piston seizure.

To fix it just let it sit over night with the air filter/lid off in a clean environment. Second change the sparkplug chances are its now fouled if you flooded it. Lastly if it does it repetitively then take the carb off buy either a kit to rebuild it, clean it and put a new gasket on it or buy a new carb if there not to expensive. (this is based upon model of bike and age) Normally carbs are pricey so i wouldn't recommend this unless it needs one or is old and would be more econmical (no sense n fixing something thats just going to break again) to buy a decent used or new one.
