The part that connects the cylinder head and the carburetor is called an insulator. It is the passage that sends the vaporized mixture of air and fuel mixed in the carburetor to the engine. It is made of rubber to prevent the heat of the engine from being transmitted to the carburetor, and also for productivity and cost reasons.
Although it is a genuine part that is durable, it is made of rubber and will eventually deteriorate and crack over time. When the insulator deteriorates, symptoms such as cracks in the rubber, unstable idling, and slow engine speed reduction will appear.
Air may be sucked in through the deteriorated cracks (secondary air), causing the mixture ratio to go wrong and resulting in engine malfunction. If deteriorated insulators are left unattended, the mixture may become thin and cause the engine to blow, so extreme care is required. If your spark plugs are turning white even though you have not tuned them, be careful.
If you purchase insulators as genuine parts, they will be expensive, so we recommend replacing them with affordable, high-quality aftermarket parts. After replacing them with new parts, you will be able to experience the engine's revving up as if it were a new car. We recommend replacing the insulators to ensure that your beloved car will last a long time.

If the insulators deteriorate, symptoms such as cracks in the rubber, unstable idling, and slow engine speed reduction will appear.
Air (secondary air) can be sucked in through deteriorated cracks, causing the mixture ratio to become unbalanced and resulting in engine malfunction.
If deteriorated insulators are left unattended, the mixture may become lean and cause the engine to blow up, so extreme care is required.
If your spark plugs are turning white even though you haven't tuned them up, you should be careful.
Purchasing insulators using genuine parts would be expensive, so we recommend replacing them entirely with new, affordable, high-quality aftermarket parts.
After replacing it with a new part, you will be able to experience the smooth acceleration of the engine, which is like a new car.
To ensure that your beloved car lasts a long time, we recommend replacing the insulators.
