It ran rough but idled pretty good. Since all 3 carbs were completely disassembled I had put the metering rod spring under the power piston arm instead of on the top. The drawings in the kit instructions did not show the spring position, so it was a guess.
The pic is of one of my parts carbs and how the spring should be positioned.
