Since fitting Lumention ignition last year, V8 sweetness and light has reigned until returning from the Clacton Show in May, when an increasing flat spot has developed from stationery. Really long (and dangerous) pause before normal service resumed, but still pulling strongly through the rev range once away. Tickover also lumpy (500rpm or so) and prone to stalling , so dashpots filled, however, haven't yet had time to take out on a decent run to see if this has helped (still stalled when I got home). As I say, once off the line, running fine. Any thoughts (as I am no great mechanic)?
Many thanks as always.
