The plugs of racing karts are susceptible to carbon fouling, but how does Iridium Power do in this case?
We frequently hear that Iridium Power is resistant to carbon fouling compared to plugs from other companies. However, there is no way that they are a 100% solution, and it's good to know these techniques to prevent carbon fouling.

When rolling in the race, close the carburetor's low needle or pinch the fuel pipe with your hand to prevent excess fuel from entering the engine.

By pumping the accelerator during rolling, a rich fuel air mixture goes into the engine, making it easier for carbon fouling to occur. Operate the accelerator gently.

If carbon fouling happens while running with the throttle fully open, this could mean that the heat range is too low or that the fuel mix is to rich. Consult with a kart shop to find the optimum setting.
