He had a fun little project going there. Of course, he’s a lot smarter than you were lead to suspect. Your first clue might be the 3D printer in his workshop..

Lean mixture could only happen if the carb could pass proportionally more air than fuel. I suspect that the lack of an accelerator pump may come into play. Emissions were never mentioned, but he was trimmed to run stoich at 14.5:1. He does mention that it is well down on power, but apparently it maintains enough power to run 80mph - just takes a while to get there.
 
Provided some help to guy here in NZ, 202 ci Holden , lawn mower carb. Had to have local knowledge of road to build up speed to overtake others, biggest killer I found was in traffic as it was always the slow guy in a row of other traffic, but yes it was a miser on gas, would have been better to rework engine with info gained. Could probably get slightly more user friendly with a staged 2bbl and pay more attention to the emulsion tubes etc of the primary barrel.
