I have just bought my dream plane. A Kitfox 5 with a Franklin PZL-F 4A235B31 engine. airframe and engine 260hours since new.
I flew her with my AMO and friend from Johannesburg (South Africa) to East London in 6.3 hours this last weekend.
We experienced some small power/consumption/mixture issues (I thought through not enough flying in the last 2 years - 20 hours). On going over it now, we see that it has an Ellison throttle body on it. We have taken out a carburettor from a C150 and are in the process of installing it to test. AMO friend hates throttle bodies. Now the original builder was quoting figures of 2300 RPM at 6000ft burning 14 litres per hour. And 2550 RPM at 6000ft burning 24 litres per hour.
Does anyone think I will get near these figures with the carburettor, or must I stick with fiddling around with the throttle body?
Was the original builder smoking something to have got these figures?
Does anyone have any advice that you could give the "fellow in the bush of darkest Africa?"
