[DML] Re: DeLorean Ignition Advance Off Idle

["content22207" <brobertson@xxxxxxxxxxxx>]

I was talking about the jolt to the ignition. Goes from 13 degrees
BTDC to something off the scale immediately.

I much prefer progressing advance with RPM's.

BTW: I am at the house now, looking at a B28F throttle assembly. On
this particular rendition only the driver's side is drilled & tapped
(passenger side has an unused cast bung). Blowing through it ports
vacuum just like a carb -- plate closed is upstream, gradually moving
downstream as the plate opens. Would be an ideal place to attach spark
advance.
