Can anyone advise if a 1962 FB Fulmar should be fitted with a kill switch. My one did not have one on arrival so I block the carb off for stopping the engine or purposely stall using first gear - neither desireable if an emergency stop is required. I ordered a FB Fulmar BMS manual and the wiring diagram does not show one. I have also shorted all three of the low voltage wires coming from the alternator/magneto to the chassis and the engine continues to run.
It just seems strange a bike would not be fitted with an electrical stop. Any advice or suggestions would be great - even if some one has retro fitted such a device connection detail would be really helpful.

This discussion has taken place many times on this forum. Villiers carburettors (normally) have no throttle stop at all; the Amal carb fitted to your engine does have a throttle stop, but the design was used on both 4 and 2 stroke engines so included this feature.
2 stroke engines will normally tend to 4 stroke on the overrun unless the throttle is completely shut, hence the lack of a throttle stop.
The above may seem odd to those used to modern bikes, but we are talking about 60 years ago when the world was different! Sandy
