Ok built about 10 of these and this is the best way,
take out the fuel system you have get one robart super filler this is a black fuel valve that when you open it it closes of the fuel to the carb!and when you close it it turns on the fuel this is important that you dont flood the motor when you start the engine you start turning the motor before you close the valve and when you shut down you open the valve, get a 32 oz soda bottle, use the cap that comes with the bottle just drill two holes for the brass pick up and air vent then use the Sullivan tank stoppers, glass in a brass u shape 1 " plate by about 5" long on the inside top of the fuse bend the ends so when you place the soda bottle in it you will hold in place with rubber bands this makes it removable! use the small header tank in the cocpit area , connect the vent of your main tank soda bottle to the pipe pressure fitting(I would replace that #5 Byron with a weston) connect your pick up on your main tank to your vent of your header connect your pickup on your header to your robart filler in nipple, your robart out nipple connect to you BVM mixture control if you dont have GET ONE and your mixture control to your carb run 5% wildcat fuel only, and mccoy #9 plugs you need to lean the low end allot on the os 91, and run the high end rich ,dont lean out the high end, lean the high end tell it peaks and back it out untill it drops off and is smoking allot the engine will lean out after the first lap,the last plane I set up this way it never ever quit! GOOD LUCK I learned to fly on a Byron f-16 passing the radio with My instructor JACK JET tapping my shoulders on which way to move the stick...
