Rinse all carburetor components in a bucket of clean water, and allow to air dry completely. For small holes and vents, use a can of compressed air to remove any excess moisture. Reassemble and replace.
Soaking is a great way to clean carbs, and a lot of the time this is sped up by boiling them. Many people will simply use vinegar or even lemon water to boil clean their carbs.
The superheated water will turn to steam, and can help wash out carbon and clean internals. The engine will struggle to run as adding water reduces the amount of fuel and air, as well distorts proper air/fuel atomization. This is why it's best to keep the RPMs up.
WD-40 allows you to clean your generator carburettor within a few minutes without spending additional time and effort. The potent liquid uses a solvent formula for breaking away carbon contaminants within the carburettor, providing you with a clean and healthy machine in no time.
When nothing happens, you turn on the choke and continue pulling until you detect the familiar smell of gasoline, which means the engine is flooded. The conventional remedy for a flooded engine is to let it set for 15 minutes or so to give the carburetor time to dry.
If water enters the engine it can lead to bad things. If there's water in your engine, it leads to compression issues because there's no place for the water to go. Piston rods will begin to bend and eventually break.
However, it's important to use a non-corrosive cleaner which doesn't harm or degrade any plastic or rubber pieces on the carburetor. You should avoid using vinegar, because the acetic acid makes metal susceptible to rust.
If you opted to buy a chemical dip, you can place your carburetor parts in it to soak. Alternatively, you can spray carb cleaner throughout the various channels in your carb (such as the spots where the jets, float pin, and air and idle screws were). Also spray cleaner through any dirty jets.
Mixing Methyl Ethyl Ketone MEK with xylene or alcohol (90% isopropyl) will also make a decent carb cleaner that helps dissolve the gunk buildup on your motorcycle carburetor. WARNING: Most of the ingredients used in carb cleaners are dangerous chemicals.
Too much fuel in the air/fuel mixture can make your vehicle surge, sputter, or even stall. For example, if the carburetor is set way too rich, it will push enough gas through to the combustion chamber and flood the engine. Your engine power might lag if the engine is being flooded while you're driving, as well.
The “Bog” simply means the engine is not receiving enough fuel when you go to wide open throttle. While there are other issues that may cause similar reactions within the carburetor, often the problem can be traced back to the accelerator pump system. Incorrect adjustment is the typical culprit.
A weak accelerator pump, worn throttle shafts, or dirt inside the carburetor are a few of the problems that might be causing the poor air/fuel mixture. Another recognizable sign of carburetor trouble is rough idling .
How Often Should You Clean The Carburetors? If you do not use your bike that often, then once a month (or even a year) should be enough. But for those constantly engaged on dusty roads, try to clean the carburetors every two weeks.
With engine running:
Carburetor: Spray to both ends of the choke valve shaft while working choke by hand. Spray down and around the carburetor throat to remove deposits from the throttle plate area. Do not spray down carburetor throat with engine off.
Use Carburetor Cleaner
Next, it's time to pick up a carburetor cleaner to get rid of the deposits within the carb, which can clog both air and fuel passages and interrupt the performance. Fortunately, you can generally do this without even taking the carburetor out of the engine.
But the good news is carbs are relatively easy to clean so the task should be near the top of your 'jobs to do' list if your bike is playing up. Problems generally arise because carbs rely on fuel going through very small holes, which can be easily blocked by gunk.
