Yes, it could use some sprucing up. I get the impression he stays pretty busy just based on his reputation, which is a good thing. Here's a picture from the website of a Onex builder who bought a Hummel/Casler 2400cc engine. I see a magneto going to the top plugs. The bottom plugs look like they are fired by an ignition system triggered by a unit in the distributor hole--maybe this one from Great Plains ($470, incl plugs). If so, the engine could be hand-propped using the magneto, then turn the secondary ignition on >after< the engine is running. I can't tell much about the heads Scott is using from the photo. There's a lot of other stuff to like about the engine, though. (The oil cooler on top is just the way it is typically set up on the Onex, it could go anywhere).
