I'm interested to see what you've found out as I'm starting to build the same plane.
 
flew her on friday and saturday. engine temps were good. the motor is rich, and it has new rings and carb, so i have to take it easy on her for now. it was doing a strange thing, seemed like it was starving for fuel after 6 minutes of flying or so, so i brought her home and re did all the fuel lines and changed the clunk out as well.



maybe monday or wednesday i will fly her again.
 
i was discussing this with someone, and they said that the cowl on a Yak should not be open, being that it helps slow down the airplane on downlines or when landing??? anyone know if there is any truth to this?

I flew my EF 110" Yak for years with it open, DA120 stock mufflers and no problems with over heating or anything. It also shows off that expensive motor pulling it around.
