Erratic Timing
Some more points on the timing curve will be really helpful. hint hint
:poke:
Does timing stay at 10* BTC when the engine slows to 600 rpm?
Big difference if it looks like this.
versus.
If the timing is advancing between 600 and 750 rpm, that would help explain the reason the engine rpm dropped so much when you put it in gear.
That's easily correctable, but we need to know before making corrective actions.
If the timing is not advancing until 750 rpm, that's fine, but if so, it may too much above 1600 rpm as illustrated in the last graph. Again, once we know this, we can choose the appropriate adjustment.
