Hay guys, I made my statement based on a few conversations I had with 240’s and 260’s owners. Also Lust, Then Love The Story of the New Z by Ron Sessons was also a source of information. The book had stated, Leaner carburetor settings lower compression, and carburetors more prone to vapor lock bedeviled all cars with reduced power and poor derivability – particularly frustrating in a sports car like the 240Z - page 16. The 260Z was quicker then the 240 but still suffered from carburetor vapor lock - page 23. As the name suggests, the 280Z had a displacement of 2.8 liters, achieved by stroking the 260z’s motor by 3mm. Despite an emissions-control inspired 8.3.1 compression ration, output climbed to 149 horsepower. “No doubt the replacement of the Fussy carburetors with Bosch L-Jetronic fuel injection had something to do with that – page 23. Sorry if I stepped on any toes with my statement.
