@dipascale posted:Rene, maybe the connection of the pertronix box in the car, I think for example who should not connect the original blue/black wire which goes from the coil to the rev counter.
The blue wire from the rev counter is connected to a specific wire on the box, in fact it doesn't work but I'll see about that later.
I will try with the old point distributor since the Pertronix 510 box can work with it, so I will check if the new Chinese distributor is responsible or not; moreover I will be able to adjust the advance easily at the stop without needing the stroboscopic lamp.
