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..

I wonder if he's going to get a job offer out of this.

 

[Larry L.]

The tech stuff went over my head.
Here's what I heard:

'Wish he'd have mentioned WHICH lawnmower brand carb he used...or maybe I missed it. I did F.F. 2 or 3 times...

haven't watched this vid, but how us he getting that kind of mileage without running it super lean, and creating NOx as a result?

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.
