does your tach have lights in it?it may be low oil or a wire grounded to the heat sensor,i had a 150 the fuel backflow fitting on the tank caused the restriction alarm,it would run up 3500 rpm all day open it the alarm would sound until you back off throttle so if it is constant without starting the motor i doubt it is fuel restriction,check the temp wires on the motor for rubbing,check oil and oilsensor in tank.i'd tke to a dealer and have it checked if you dont find anything
