I have a 1985 190e 2.3l california version. wanted to reset timing due to ignition ping. my question is how does the scale on the balancer read? I can see the 0 mark and the pin for the sensor, but is the scale in 2 degree increments or what? right now when I put the timing light on it the pin on the balancer is on the indicator. is this 13 degrees btdc.? it pings at freeway speed under light load and pings under hard acceleration above 3500 rpm. I need to cure this ping, high octane fuel did not help. thanks for any replys
