What causes knocking under load in a Jabiru Engine?
- AAnthony CollinsSep 13, 2025
Knocking under load in your Jabiru Engine can be attributed to a few key factors. The octane rating of the fuel might be too low, or the fuel could be old or stale, so use fuel with a higher octane rating. Ensure that each spark plug is fitted with a sealing washer. Heavy carbon deposits can also cause knocking, so remove the cylinder heads and remove deposits in the combustion chamber, and determine the oil consumption.
