2000, 50hp, 4 cycle ,Bigfoot, was running perfect. Now that the cold weather has arrived it starts right up and as engine warms up rpm's will increase to around 2500+ and won't drop down. I shut down engine, restart, starts right up and again the rpms will increase as the engine warms up.
Has anyone experienced this issue?
Is it an electronic problem?
Last few times I will start the motor and take right off and not allow the engine to warm up.
