Following on from the SB needle install I decided to adjust the float level to factory.
Previously I had the float level a little higher as a band aid fix to richen the top end mixture of the SM needles. The rear float bowl gave me grief. I think I had the lid off 20 times before the geometry of the float was massaged so it wouldn’t stick in the bowl not closing the jet properly. I got there in the end. When you bending little metal tabs minute amounts you need a good swag of patience.
Using the float sync tool and a trusty bit of clear pine dressed down to 9/16” thick the floats are set to the same level. The Nissan workshop manual suggests making one float higher than the other, presumably for G forces under acceleration, but I’ve never done this.
Working on the 240Z is not the highest priority in my life (although I wish it could be!) so road testing and datalogging with the Innovate LM2 wideband will have to wait. Video below.
