Hi,
is there a website that could tell me the age and fuel mix of the mercury 50hp thunderbolt ignition i have just bought from the serial number. Also, the engine fires up ok and idles well but as soon as the throttle is pushed forward, it seems to die. Any ideas???
Thanks in advance
Andy

Re: Mercury information

Andy, Mercs will die when the throtle is advanced, if the carbs idle mixture is set too lean. Richen up the top carb 1/8 turn (CCW) and try it. If it still dies, open the bottom carb 1/8 turn and try again. if it still dies repeat the process. Eventually if the motor is sound, it will rev up well from idle and idle reasonably well. BTW the gas-oil mixture is likely 50::1, unless the motor is from the '50s or older.
