In this installation, all you have left to worry about is the tank. Remember 80% of your engine problems are the tank and the other 20% are your tank. You will actually get more (good) run time with a smaller tank installed correctly than with a big one installed incorrectly. always make sure you have 1/2" of dense foam around the tank--front, sides, back, bottom, everywhere--such that nothing can touch. Then pack it lightly inside the nose. If you wrap the tank, then cram it into too tight a place, then you defeat the purpose of the foam. Place the center of the tank at the center of a a side mount engine and carb or at the center of the fuel outlet of a more vertical engine (I do not buy airplanes that are not side mount--not worth the trouble of getting the tank right). Finally, if the tank is clean and there are no leaks (make sure the needle packing nut is tight) you will not have any fuel flow issues.
Finally, this engine runs a 11 x8 for break in. Run it up to peak and back it down at least 1000 rpm, then sneak up on the setting until it is running nicely in the air, transitioning fast, and not blowing plugs. After you get the setting close, you can try the 11 x8, 12 x 6, or the 12 x 7. If you start getting heat, or have trouble backing down the needle a full 1000 from peak without falling off the pipe, then your prop is too big.
