I wouldn't get real technical with your Avid. These are simple airplanes to own and fly if you have the wide landing gear and Matco tail wheel. I have the Artic Sparrow mixture control. At run up I richen the mixture until it starts to miss, then back off one turn on the mixture control until it runs smooth. On take off full power, cruise 5950, when its time to land I run cruise power until I know I have the runway made, then back to idle until I flare, then add a little power and let it settle in. I never run it at mid range.
I think a lot of people convert old boat trailers. This makes it easier to put the main gear ramp towards the back of the trailer rather than put a main gear ramp running from the back towards the front. I built mine to tow facing forward.
