We go to a track on Route 61 in Delmar, Iowa. Just north of Delmar is the town of Maquoketa, home of the Clinton Engine. Great museum and you certainly can learn a lot from the tour. Worlds BIGGEST ENGINE builder was their claim back in the 50's, bigger than Briggs. They use to send their engine out on shrink wrap for a father /son assembly project. Lot to see and read on the tour which was in the old office building of the company and it is well stocked with just about everything they made. Never realized they were so diversified
