(2) It was stumbling when I gave it throttle. I changed the acceleration pump nozzles to 37s and I think that did the trick. (3) Plugs fouled. My first coil was out of spec and I replaced it, and hope that did the trick.

This is a pricey engine and I want to make sure it's operating within range for a carb'd car. With a sideband, I can verify and optimize.

Also, the fuel was percolating when I stopped. I added a 0.25" phenolic spacer and I *think* that fixed the percolation.
