Hi,
Well I have a waco bi-plane and its a smaller plane so I have a magnum xl .28 on it right now and i have it mounted upside down and a little to the left at a slant and the gas tank is in the right side up. I cant seem to keep it running it dosnt pump the fuel thru the line if i cover the muffler and it pumps fine and I have put a check valve on it and that gives to much pressure. I have a .40 motor and im thinking about putting that on there but that may be to much. I have also put a baffle in the muffler and that didnt do it as well.
If anyone can help that would be sweet!!!



KEP HER IN THE AIR!!!!!!!!
