Today, a hot and humid day in Ontario but ideal for a run with the 50cc Lem for my grandson. Started well and he had a great time until after a minute or 2 break, he was unable to start the machine. We added gas as we thought that could be the issue but still no luck. He did run through a lttle water on the gravel road but I would not think that a serius issue. We thought maybe we flooded it but still it should have started eventually. Any thoughts.
