280i Timing Marks
Discussion
I have 7 points on the static timing mark on my engine....
The Haynes manual shows 5 timing increments ie 03,06,09,12,15 and recommends 8 degrees BTDC. I've marked the 3rd one in on the assumption that this is 9 degrees BTDC but how do I know for sure what the pointers on my static marker indicate? The plate is too corroded to read off any markings.

I don't know whether you have a composite pulley on that one, but for example on the RV8 it's quite common for the outer part of the pulley to shift relative to the boss so you can't take the timing marks at face value. I've even seen an engine where the fixed marker was in the wrong place. Unless you're already certain the marks are accurate, just take five minutes to find mechanical TDC and that eliminates all doubt. It would be a shame to spend time fine-tuning the ignition and then find out you were working from a bad reference.
