Feedback.....Finally got the Riley out for a drive - really pleased with Diistibutor.. The result is consistent with what I discovered when I fitted one to an Austin Light 12/4 a few years back; pulling away from rest the car seems more ‘urgent’ - it seems more willing to rev and at speed its noticeably smoother. It seems quite happy where it's set so I think I’ll leave well alone now.

Cheers, A
