On the Kazuma 110 Falcon, the spark plug is in the front of the engine off set a little behind the front tire. When driven through water, the water from the tire is channeled right into the spark plug area.

We had a heavy rain and our dirt circular drive had about 2"'s of water and my son decided to have some wet fun. He didn't even make a full circle around when his Falcon stalled out from the water. How can I better protect the spark plug area from water??? Heavy coating of grease? Is there another type of boot I can fit into the area? Any suggestions?

thank you, Teej
