Before taking apart the carburetors, look for the assembly diagrams in the service manuals for your reference. The kits may be or may not include the instructions and assembly diagrams. You must also look the location and connection of various lines and hoses. You can either draw a picture for remembering the connection of hoses or just mark on the hoses for their connections.
You must lay all the parts on clean tray or work bench and pay attention on the connections of part as well as how they came particularly the linkages so you can recall the way to reassemble its parts at the time of putting it together. Look out for the check balls of steel that are small so they cannot be lost or overlooked.
For cleaning the parts of carburettors, you can use the carburettor cleaners as well the solvent which neither may nor damage the plastic of soft parts of metals. Use rubber gloves for avoiding skin contact with the solvents or disc brake cleaner as well as use it in the open area for proper ventilation. Don’t breath out the fumes.
Look out for the throttle shaft that is worn. Base casting has a hole that worn out with passage of time that allows air to suck in the shaft. Fuel mixture will lean out that will cause stumbling issue, hesitation or misfire. If the hole of the throttle shaft worn out, the throttle shaft will be removed for fixing it, oversizing the hole by drilling and installation of brass or steel sleeve for restoring the normal clearances.
You should also monitor for the bad float in the vehicles’ fuel bowls. Shake the float to check the presence of liquid in it if it is of brass. Even if the seam has small hairline crack, then the fuel may seam inside the float, letting it to sink and providing excessive fuel to the engine. The majority of carburettors have the plastic floats in place of brass. The plastics my soak the fuel similarly to Sponge over passage of time that make it too heavy. It will cause the float to have low ride in a fuel bowl which will provide excessive fuel to the engine. In case, this is your scenario, you must look for the replacement of your carburettors when they get bad or heavy float.
