ues in the ECM.

TPS will determine the basic parameters for all
fuel and ignition mappings.

position sensor (TPS) is loosened or removed or
carburetor or ECM is replaced. An improperly set
TPS may lead to poor engine performance.
Ensure carburetor synchronization and throttle ca-
ble are properly adjusted prior to performing this
setting. Refer to FUEL SYSTEM.
IMPORTANT: Having enough free-play in throttle
lever is critical to properly set the values in ECM.
