The NTSB's narrative final · quoted from the NTSB record
According to the pilot, just after rotation the engine lost power and subsequently impacted trees between two homes. Examination of the engine found normal operational signatures throughout. Examination of the carburetor found that the carburetor accelerator pump did not operate when the throttle was opened. The carburetor was disassembled and the accelerator lower check valve was found contaminated with rusty debris. The acceleration leather plunger was found hard and red in color, similar to the rusty residue. The leather plunger did not fit tightly in the acceleration well. The carburetor bowl exhibited rusty residue in the lower portion. The float level was not measured, but visually appeared normal. Additionally, weather conditions were favorable for the formation of carburetor ice at the time of the accident.
