I finally got around to Drip Timing my IP and decided to try the “Doktor Bert” suggested advancing of the timing to 28 degrees.

I was surprised to find that there is no degree marks between 25 and 30 degrees on my Crank Damper; making it somewhat of an educated guess that I ended up with 27-28 degrees.

(Note: Injectors rebuilt 1 year ago with Monark nozzles and no previous smoking issues.)

My Engine was not happy with this timing. There was some nailing at idle until the Engine was partially warmed up. There was also some wispy barely visible whiteish gray smoke that I did not have before I changed the timing. Otherwise the car ran fine. It did seem like it was slightly peppier.

Since I had marked where the where the IP started from and where it ended after I had advanced it I decided to split the difference and retard the IP ˝ of the distance I had moved it.
After doing this the cold Engine nailing disappeared but there is still a slight trace of that whiteish gray smoke. This is where I decided to leave it.
Doktor Berts’s comment idle noise and proved true and it did feel a little more responsive: “The slight amount of advance definitely improves low rpm throttle response and overall smoothness of engine operation, although it does increase the noise of the combustion process slightly at idle.”
