There are a lot of bikes, but none of them can run without the carb and the correct settings. It is a device for mixing gasoline with air, and depending on the proportion and amount of both is the correct and economical operation of the engine.
Our item is set up so that the gasoline enters the float chamber, to a certain level, which is limited to float. He, rising, closes the passage for the fuel shut off needle.
Then the fuel enters through a nozzle into the mixing chamber, where it mixes with air and enters the cylinder under the action of thrust when lowering the piston down. The quality of the mixture depends on the engine.
Schema of the carburetor K-62 should be known to everyone who is going to work with this device.
An Important function to play the jets, they perform a major role in the amount of fuel delivered to the engine. Possible to install different jets in the carb-To-62. Technical characteristics thereof allow to work perfectly on smaller jets with low fuel consumption.
Depending on the quality of the mixture we either receive a powerful but economical engine or motor without a good torque. In the case where a strong deviation in one direction or another, the engine can not work normally.
If you have problems, for example, the engine will not start if there is spark and we believe the compression in the engine is sufficient, you can use a candle or a gasoline fill fuel cylinder through the plug hole and try to start it, it will help clear the passages in the carb and clogged the jet.

If the engine does not start, you can try to start it, pushing the bike in neutral with ignition off. When the speed became steady, and the bike gained sufficient momentum, you should turn on the ignition, depress clutch pedal to start the switch in position 1st speed and slowly release the left lever on the steering wheel.
If the engine starts, but stalls when a sudden lifting of the throttle or lowering, unstable idling, the carburetor should be carefully viewed.
Prior to removal from the engine of a mechanism such as a carburetor K-62, click on utopias float and make sure fuel flows to the carburetor (gasoline has to go through the hole under the button), and the reason for the poor performance exactly in the carburetor.
If gasoline slowly enters the float chamber, the cause of the poor performance of the carburetor may be clogged filter benzocane. It is sufficient to Unscrew the glass of the clarifier (a cylindrical vessel with a screw from the bottom), it can be clearly seen at all benzocane motorcycles, and clean the filter.
The Carb-To-62 can not work well due to late podlivaya liquid oil in air filter or clogging. You should try to start the engine without a filter, if the work will be better, it should be cleaned and rinsed in kerosene.
Disassembled the carb-To-62 photo in our paper allow to consider in detail.
We will need the following tools: a minus screwdriver, keys 12, 14, hex head 6 or pliers. You must first remove the screws securing the carburetor to the engine by the key 14, then the top cover with a screwdriver. With the throttle out of the housing, removed the motor Assembly and screw the IAC, which has a flat end.
Then Unscrew all the screws, including the screw of quality of a mix, and remove the cover of the float chamber, it is secured with two screws – one on the left side of the cylinder, there is a button utopias of the float, the screw of quality of a mix and hose for fuel supply; another – from the opposite.
Turn the carb upside down, inspect the float, it needs to be a few degrees above the beginning. The base should be tongue, if the float is wrong, should be tucking thereof to achieve the desired effect.
First, take out the axle of the float, look for wear, it should be the same throughout its length. Remove the needle locking of the float, it needs to be a small silicone gasket. Then Unscrew the main Central jet of a key 12, after which the head 6 or pliers, Unscrew the idle jet, it is fixed with a locking washer.
A Smaller nozzle, it is important to tighten during Assembly with a locking washer, otherwise it will break. Carburetor K-62 is produced without the concentrator, they go for brands starting with K-33 and K-38, there he is in the corner and gets out with a screwdriver.
After vikruti of the nozzles on the back side is removed is a Central guiding flap, which is held by the main nozzle. For best performance, you can sand the throttle and the Central element. If the inspection is not for immediate installation on the engine, then you need to lubricate all knots with oil. Reassemble in reverse order.
When buying a kit on the carbK-62 should pay attention that the holes were free of defects, and the nozzles it is advisable to choose either to replace. There is often a discrepancy between the instructions and actual size of the holes, especially if the jet is made in China.
The Carb-To-62 may work with the jet from grade K-55, they are installed on the motorbike ‘Sunrise”, as practice shows, on the engine it is not particularly affected, but with careful driving possible more economical fuel consumption and less engine overheating.
When installing the carburetor on the new bikes may need an adapter, it is quite suitable machine, you need to drown out the extra hole you can see it well in the photo below.
But you should consider the size of seats in the store, it is advisable to take the carb with you for example, because standards may differ, and we have to go back.
Jets carb-To-62 look at the light, in case of blockage, clean can and a match, but non-metallic wire. You need to rinse with a special solution every hole, and the lid of the float chamber.
There is a special spray with a thin nozzle, it is best to clean the carburetor. Done partial disassembly, left the jets, and a mix of instant cleanup and purge all channels.
Wash and wipe well the upper and lower cover. Heavily soiled carburetors can be cleaned in kerosene, then blow it with a compressor and a spray to completely clean the element.
On Top of the needle retainer installed in the middle position, if you need a cost-effective operation - at the bottom. The engine is difficult to start, but will become more economical. The throttle plug-in neck to the air filter. It should be easy and free to move along the guide plate.
After the preliminary adjustment of the position of all elements, selection of the jet, clearing all channels should be screwed to the carburetor to the engine by the key 14, to attach the hose, the cable (from the throttle) to the flap, the screw of quality of a mix, next to the fuel hose until it stops, and Unscrew 2-3 turns.
The screw amount of mixture to the maximum, it relies damper when lifting, it must be inserted in the groove near the cable throttle. There is also adjustment of the concentrator, it can either be attached to the carb, or the cable from it going to the steering wheel. The concentrator is a needle which opens an additional channel with fuel.
To open the dresser by about 1 cm, click on utopias float, gasoline should leak through the hole, then turn the ignition on, the light shall burn bright, and add a little gas, push the kick-starter several times.
If the engine starts and immediately stalls lazily, the cause is either the quality of gasoline, or a weak battery. In the case when the engine does not start, inspect the main wire and a candle, it can fill with excess fuel, it should Unscrew and clean.
To check the spark it needs to be applied to the cylinder, turn the ignition on and press the kick-starter, the spark must be strong and overcome with equal force using the exact time.
How to adjust the carb-To-62 for normal operation? First, after starting the engine, turn the concentrator. Further adjustment of carburetor K-62 is by means of two screws – the quality and quantity of the mixture. Gently, gradually tightening the screw each time a quarter turn, until the minimum stable operation of the engine.
Then repeat the same procedure with the screw of quantity, gently loosen it until the engine starts to gain momentum, and then screws it in turns to spin to the lowest sustainable speed. Proper tuning of carburetor K-62 is not of the user, and the operation of the engine.
The Factory setting and recommendation is that the screw should be unscrewed exactly one and a half revolutions, it is in practice found not always, because the engines have different compression and deterioration, which can not affect the carb, so you need to set at minimum stable engine speed.
Adjusting the carb-To-62 takes place on warmed-up engine. It is important to ride a bike a certain distance to the engine is well warmed up along with the carb and the entire system. Then diminish the gas to idle and begin to re-configure the same pattern. It will provide excellent tuning of the engine, minimum fuel consumption with good traction.
Especially it is important to warm up the motor on the go with the new parts in the carb, or to the exact and final settings. If you don't do the carb adjustment on a warmed-up engine, it will not work correctly.
The Engine will give enough power with a sharp lifting of the throttle or fuel consumption will be too large and the engine will overheat. It is possible, even if the setting is made correctly, but bad the engine is warm.
You should Then try to touch the crankcase undercylinder, it should be warm but not hot. Some sample cylinder, it is a mistake to define the normal warm up all internal parts, only Carter to the touch.
After a sufficient warm-up, repeat the setting screws, the rpm's should be minimally sustainable, otherwise the engine will overheat, and it should not arbitrarily stop after a while.
Carburetor K-62, despite some adverse reviews, it is well-proven in practice. Its simplicity, reliability and ease of use won the hearts of many motorcycle owners. It is quite competitive compared to many foreign peers and more modern models.
