Today it's a very hot day ! I run my Peugeot 103 10miles at 50/60km/h.
When i do 8 miles the motor stop to run and he make a backfire (1). I try to start the motor but i can't ! I whait 5 minutes and he start and it was fine for the end of the ride !
It is possible the motor was to hot ???
Or my spark plug is bad (b6hs NGK)
