out in Colorado i still have to do an emission test. these are the fuel mixtures they came up with. this is on a scout II 345 4bbl carb at 5400 feet and 88 degrees out side temp.
maybe some of the fuel injection guys can tell me if im still to rich of a mixture.

idle mixture 653 RPM 14.1 fuel ratio

cruse mixture 2331 RPM 13.2 fuel ratio


any idea on those numbers ?

thank you
 
Moved to a more appropriate location for better exposure.

The techs at the sniff station wouldn't tell you anything? Did they give you a printout? I would think you could take the printout to any local mechanic and have them make sense out of it for you.
 
thank you

ya the tech gave me the print out and i used a converter to come up with the fuel ratios
 
hey
limits are 6% i passed pretty east
limitis on HC are 1000 i had 256 HC
