What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The aircraft departed lmt (Klamath Falls). PIC described a procedure he has been using to work around an issue with the carburetor, acceleration and full power. The procedure he described was to advance the throttle slowly until the last quarter then rapidly otherwise the engine would not throttle to full power.
The PIC stated that the newly manufacturer rebuilt carburetor was installed, would not accelerate propoerly or achieve full power so it was removed and sent back to the manufacturer, rebuilt (again) and reinstalled. The issue was lessened but still present.
On departure from lmt the PIC reported the procedure was used, takeoff and subsequently the engine wuit on climbout forcing a landing in a field. The field was soft and the left main landing gear collapsed upward causing damage to the left wing tip, aileron and gear attachment areas.
