Tom, I'm thinking at this point that it might be a little too advanced because of what sounds kind of like what pinging or pre-ignition would be in a diesel, if there is such a thing. I wish rotating the IP would be as easy as rotating a distributor on a gasser. That way I could adjust it while the engine was running. I'll have to just try and see what setting will make it run best.
I thought that since the car has had a solid history of 3K mile oil changes, (Everyone: please, no oil discussions here
) it shouldn't have much chain stretch.
