Hey folks!
File this under the "novice shade tree mechanic" rather than specifically rover...and in that regard, I'm grateful for all the handholding and patience in this forum!
I've been curious about the procedure for setting timing for a while. While re-reading the WSM for my 2.5L petrol last night, I noticed the following:
From those specs, do I understand that i:
get someone to rev the engine to 2,000 RPM, disconnect the vacuum pipe to the engine and use my timing gun to time it in?
If so, help me understand 16" before top dead center - I get what BTDC is, but how do I measure that with my gun and the notches on the wheel? I guess what I am missing is that my notches aren't marked in any way. Which is 16 BTDC?
Now I've also tried the "ear" method and its close cousin, the beer method. What is prompting this question is how loud my engine seems right now. Based entirely on my own opinion, if feels like its just running too high currently. When I dial the timing back by ear, it sounds better, but begins to backfire at deceleration. It is also dieseling again - but suspect that is unrelated?
Looking forward to the education - thanks all!

- what is dynamic? Does that simply mean engine running?
- 2,000 RPM - really? Unless my tach is installed wrong (hey, nothing wrong with a few luxuries) I only hit 2,000 going 65 with the peadel floored. That seems like high revs, no?
- vacuum pipe disconnected - which one? The advance on the dizzy or the one to the engine?
