AURMTF001 Analyse and repair performance carburetted fuel systems
Assessment tool
Version 1.0 Issue Date: June 2024
This unit describes the performance outcomes required to analyse and repair carburetted fuel systems and associated components. It involves identifying, evaluating, selecting, justifying and documenting the most appropriate rectification method or variation to the rectification method. It involves developing and modifying performance improvement strategies in carburetted fuel systems and associated components. The unit includes the analysis of multi-system and intermittent faults which may be caused by operating in adverse conditions.
It applies to those working in the motor sport industry.
No licensing, legislative, regulatory or certification requirements apply to this unit at the time of publication.
You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)
