Analysis

The plt stated he lost power on takeoff, but elected to takeoff rather than abort. He cleared wires but decided he could not clear trees & made a forced landing in a corn field. Inspection of the acft revealed that the fuel control rod cotter pin was separated & the fuel valve appeared to be about half on. Also, one of the spark plug wires was found to be loose. The acft was serviced with automotive fuel without an approved STC for this fuel.
