Claims8
A fuel calibration device for use with a carburetor and fuel bowl of an internal combustion engine to calibrate fuel flow, comprising:
- block means for receiving fuel metering systems;
- means forming a main well in said block means;
- main jet means received in said main well for metering main fuel flow;
- emulsion tube means received in said main well above said jet means for emulsifying fuel with air;
- air corrector means received in said main well above said emulsion tube means for introducing air into the fuel at said emulsion tube means;
- said main jet means and said emulsion tube means and said air corrector means being united in a main assembly that is removable from said main well when said block means is attached to said carburetor to permit replacement with a like main assembly having different characteristics;
- means forming an idle system well in said block means;
- idle jet means received in said idle system well for metering idle fuel flow;
- and holder means received in said idle system well above said idle jet means;
- air bleed means for metering and introducing air into the idle fuel flow;
- said idle jet means and said holder means being united in an idle assembly that is removable from said idle system well when said block means is attached to said carburetor to permit replacement with a like idle assembly having different characteristics;
- supply means for supplying fuel to said wells;
- and discharge means for discharging fuel and air from said wells to the carburetor.
