Fired mine up this morning with the `D4R85' dizzy- no kickback, obviously it has a bit less idle advance now than the 45D had (it was 15* or more...!)
<edit> After the run to kazjims via Wisemans Ferry last weekend, I can say it's lots smoother than the Lucas 45D/Pertronix combo. Maybe it actually fires all 4 plugs at the right time now...
'bye, Lucas...
I'm running approx 12* static advance, full advance is now 36* at around 4000 rpm. Sounds a lot but it likes it (it's running 1310 flat top pistons- `Mahle' forged ones, at 10.4:1 C/R, with a Graham Russell RE13 cam & 1.5 rockers)...
