OK - so now I could use some help. If I mount the motor inverted then the fuel line out of the tank is a good 20mm above the center of the carb - the Saito instructions say to keep the tank 5mm below - I have never paid much attention to this type of thing before because with planes design for glow the tank and carb align. I am assuming the carb being below the fuel line will cause fuel to drain from the tank when it is just sitting. Maybe I should mount the motor sideways - or perhaps run the fuel line down below the carb and then back up - kind of like the ubend in a sink. Any ideas?
