The '1975' units were equipped with >
* IES {Idle Enrichment System}
* TPS {Throttle Position Solenoid}

The {IES} is for drive-ability enhancement, which allows for a 'richer mixture'
during the warm-up period, as the system blocks part of the choke air-bleed to
richen the Air/Fuel mixture.

The {TPS} delays 'full-throttle' closure at deceleration, to prevent a rich condition from developing.

The 1975 Thermoquad's ran with a 'leaner' primary, as evident by the
'fatter' Metering Step-Rod {.075" Economy}
