I’m having problems with my Perkins 4.108
won’t start when cold, (we are in the tropics), unless I open the air vent screw on top of the anti stall device for a second whilst the starter motor
is turning the engine
This way it will start immediately.
It is not a starter motor
I have been battling with this for the past 400 engine hours.
The engine runs perfectly. I don’t have any, not even minor
, diesel leaks
Could there be air in the system ? I can only see fuel
dripping out of the vent screw when opened.
I assume, if air is trapped somewhere in the system, it would be pushed through when the motor is running?
Could there be a diesel
non return valve leaking, allowing the diesel to run back into the tank when the motor is stopped?
I have replaced the fuel lift
pump, it makes no difference.
Any help would be greatly appreciated.
Thank you very much.
