Hey Bob,

Where is your fuel tank located, is it in the stock position right behind the firewall or have you moved it back towards the CG and use the regulator? I have my Moki 1.8 in two planes now with the tank mounted as close to the engine as possible and never a problem with fuel draw or flame-outs. Your 24 Oz. tank sounds really large to me as I use an 18 Oz. tank and get a flight that is plenty for me (ten minutes or so with plenty left of several go-arounds). I use a BCM Pitts muffler with no restrictions in the outlets, 5% Omega fuel, an OS-F plug and have never had to land with a dead enginel [8D][8D]........RJ
