Hi Harry,

The problem is patly pointing to the fuel line. Please check that there is no restriction in the fuel system and that all filters, including the one inside the engine front cover, are not clogged. On your next run, please observe the pump battery voltage at idle and max rpm. At full throttle, the pump should be using around 5V. If the voltage is excessively over 5V, there are restrictions in the fuel system or the pump itself is going bad.

While you have the front cover open to check the filters, please make sure that the gas and fuel lines are in good condition. These lines can become brittle after 3 years depending on usage and storage time.

After checking all the plumbing and filters, recalibrate again at your next start before flying.

Hope that the above will help. Please do not hesitate to contact us direct at [email protected]
