My '77 Honda Accord runs well and gets 33-35 MPG for local driving.
However, the CVCC engine seems to run very lean and exhibits noticeably
improved acceleration with the manual choke on even after the engine
is warm. This leads me to believe that I can expect better performance
by enlarging the primary metering jet in the carb but with some
sacrifice in emissions and MPG. Since Honda does not sell jets for their
carbs, I must carefully drill out my present jet. Have any of you
auto guros tried this on similar small four-cylinder engines? What
percentage diameter increase should I try? How will this impact
mileage? Can an increase in carb float level provide the equivalent
mixture enrichment (and be undoable as well)?
Thanx
