Maintenance to be done during Holidays. Let’s try to overhaul the carb!

How to

The part that has the biggest impact on the condition of the engine is the carburetor.

If the slow system circuit is clogged, it will idle sluggishly. On a tuned engine, it won't idle unless it decides to slow or pilot jet. If you can't get the mains settled, the engine won't be able to turn up to the high RPM range comfortably. The key to maintaining and setting up such a carburetor is to make sure that the various passages in the carb body are Is it clogged? And so on.

Let's take a look at disassembly and cleaning, the first step.

Start cleaning the carbs from "Operation Kettle Boil"!

If the carb has a stuck throttle valve that cannot be opened or closed, start by boiling the carb in a kettle of water mixed with degreasing and cleaning solution in a zundue pot and heating it on the stove or stovetop.

Abandoned vehicle carbs often have a throttle body that sticks and won't come off.
By boiling the carb body in a kettle, it can be pulled out roughly, but if you still can't pull it out, use a heater to warm up the body area.

Even if you don't have an out-of-print car, I recommend Keister's "Fuel Control Kit"!

When disassembling and overhauling the carb, all of the various O-rings and gaskets should be replaced. Things to do. However, there are some older cars whose repair parts have been discontinued.
That's when you can rely on KeyStar's fuel control kit. Not to mention gaskets, various jets, jet needles, float valve sets, etc. An excellent all-in-one product.

Disassembled carburetors should be disassembled and maintained as individual body parts, not as separate parts.
You can cut containers or PET bottles that contain disassembled parts and use them as separation containers.

This is a thoroughly polished and assembled quadruple carburetor assembled from disassembled parts.

Not only is it beautiful, but after this, I installed it on the bike and set it up, and it idled supremely consistently and blew up well.
When the engine isn't blowing well or starting isn't good, the carburetor is the first part to look at with suspicion.

If the slow system passages that dominate the idle range are clogged or out of condition, engine starting will be severely compromised.
In addition, the carbs often have to be disassembled and maintained when the engine of an abandoned vehicle is started, for example.

KeyStar/Kishida Seimitsu Kogyo, a manufacturer of carburetor parts, offers a fuel control kit for various models.
For example, one of the reasons why the overflow doesn't stop and gasoline continues to flow is due to a faulty "float valve".
If the valve can't be closed due to debris or scratches that clog the valve passages, the gasoline will not stop and will continue to flow.
In some cases, the jet needles and needle jets have worn out after years of driving.
At times like these, a fuel control kit makes timely maintenance possible, as it is an all-in-one kit with all the replacement parts you want to use for maintenance.
The fuel control kit is set up as one set per carb body, so if you have a 4 carb, you will need 4 sets.

Did you know that it's a good idea to use "heat" during carburetor overhaul maintenance?
Just as washing in lukewarm water removes more dirt than washing in cold water, warming up the body when disassembling and washing the carburetor makes the work much easier.

This time, we boiled water in a Zundou pot and soaked the dirty carb body in it.
After the body is taken apart, it is completely cleaned with special carburetor cleaner.
Further wet blasting was used to clean up the body surface. After blasting, the body is warmed up in a high-temperature dryer and then air-blown into the passage It's good to remember that media can be easy to blow up.

POINT:
Maintenance is definitely more efficient with the use of "heat. When you disassemble the carb, you boil the entire body (float chamber and internal Remove parts, if they can be removed, and then get to work), each part should be effectively cleaned You can do this. I want you to try it.
