Recap:
Once you read the timing one way, flip the pickup around 180* so its facing the other direction and check again.
Most pickup (the thing that clamps onto the wire) have a little arrow showing the direction of the spark towards the plug, but don't rely on that; just check the timing both ways and then you need some common sense/knowledge of which way is correct
1. The cas will be nearly center when the pickup is flipped properly (slight offset)
2. The engine will seem to run well, normal even
3. The timing will be steady as long as the TPS is disconnected. It doesn't matter when you disc the TPS, running or not running.
4. Rev the engine and check the spread, it should advance timing to say 25 or 30* or something like that (from 15 original).
5. Always set to 15* btdc timing unless you are advanced tuning expert.
