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.
