"But no one would want to time their bike with something like that these days. A 1" dial indicator setup is the way to go."
Nowt wrong with pencil down the hole for an old British bike- fine for my side valve Ariel & my Panther.
I stand so corrected for casting aspersions on the "old" ways that have served for so many years. Thanks for carrying on with the traditional methods.
But I'll stick with using a dial indicator myself because they are so much easier for my old eyes to see. .
