Hi Guys,
I assume not to start a new thread because I am facing very, very similar problems - hope it is ok…
My Cessna C180 1955 O-470-J have faltering problems during the initial phase of the takeoff. Problems are not possible to simulate on the static run up or on the concrete/asphalt runway. She falters only when you hit any bump (on a bumpy grass runway), when you get of - it goes smoothly and no problems ocured. No problems in the air, no problems on the ground, no problems on the smooth surface like concrete. Just on the bumpy runway during initial phase of takeoff - and not every takeoffs…
In order to solve problem I went through those steps with no positive result :-/
- static fuel flow before carburetor - 110l/h (29gal/h)
- no difference on avgass or mogass
- new fuel hose from gascolator to carburetor (together with fuel metering system)
- new carburetor installed one month ago
- all vents checked
- it is same if you ran on left or right magneto
Could you please share you opinions and tips were to start again? There are not so many experienced mechanics here in CZ…
Many thanks for any tips.
