How To Measure: Cables are sorted based on the length of the outer sleeve protector, making it easy to find your cable even if the inner wire is broken or missing. Simply measure from end to end of the outer sleeve only. Note that most cables can vary 1/2” on the sleeve length and still fit. It is important to note the distance the inner cable extends past the sleeve as some carburetors require different lengths. Always test your unit before operating.
