@ Truckracer,
The communication with Rcxel is hard even for me and is not that they do not care, it is the language barrier.
They use google translate and many times the sentence come out without meaning and have to read it several times and try to switch
and put words in order, have to use simple words and nothing fancy.
The SMT sensor has been discontinued and are using a SIP 3 sensor.
I do not use them as I make my own so I can not say issues went away.
The spacing was a solution to make it less sensitive .
Truckracer...do one more test...get a 10-15-22 K resistor and solder between red and white wire. this should decrease the sensor sensitivity.
Or someone can send me one of those engines with problems, I want to look at it also and see it and hope to find more details about issue.
@Klaps, I got your email. Look at this video, it will show you a piston stop and a timing procedure the way I do it.
Also I talk about the sensors types and timing....30min.
