Ding, ding, ding - we have the winner!

My local engine builder told me it's very unlikely to wipe the fuel pump eccentric on a cam. But it wouldn't run off a gas can either. The fuel pump is BRAND NEW, so it couldn't be that, right? Nonetheless, I happened to have a greasy old zillion-mile fuel pump on the shelf, so I installed it. Sure enough, it picked the fuel right up and the engine ran fine. Incredibly, the brand new fuel pump was bad.

The build is back on track! Now that I know the motor will run, I'll start assembling the front sheet metal around it.
