Bitter Bald Guy / 1187 Ringwood Ale yeast problem

Yesterday I brewed up a batch of the Bitter Bald Guy (recipe below),
I added 1# of rice hulls as I do when using flaked cor, just be sure the sparge does not stick.
I also did use 1187 Ringwood Ale yeast since I had it on hand,
I have used this in the past for IPAs and other bitters.

The problem is it has been almost 18 hours and there is no activity, should I assume the worst and
pitch new yeast or wait it out a bit?

I have had delayed responses in the past, but never this long?
