I am building an Acey Duecy , its a parasol design , wood wing & tube fuselage . I have a cont 90 ground power unit I intend to use . The biggest challenge is the intake , my cylinders breath from the top instead of up from below . I just want an up draft carb not fuel injection . I can not find a picture anywhere on the internet to give me a leg up on this intake design . Really don't want to reinvent here & I'm shure I'm not the first to do this. Thanks for any help.
