Well I had my medical with the doctor that owns one of the subject
planes today. In our short conversation I asked what specific problems
he'd had with the conversion. He says the only problem has been with
the computer setting the fuel mixture too rich. They had a lot of
trouble sorting that out and are now running without using the O2
sensors. He and his father have owned this plane for many years
origionally with the franklin engine and later with a lycoming. He was
ready to sell the plane due to poor performance off the water and slow
climb rates but since doing the conversion he is very happy with the
performance now. His takeoff distances are greatly reduced, cruise has
increased by 5mph, climb rates are as high as 1500fpm. ( instead of
100fpm with the franklin on a hot day ) and his fuel burn has dropped
from 12 to 8.8gph. on autofeul.
