Status: online 		I would think that the only way that could happen would be if the tank is too high relative to the carby. If the fuel level in the tank is much higher than the carby, the fuel will just syphon out once the fuel line is primed. Does this help?

Status: offline 		mike, the tank is higher than the carb, for one i built the tank and it is up in the nose like the real cub and the twin engine has a bottom mounted carb. i was wondering if i have something on the carb set up wrong? it did this on the last plane that the engine was on but i didn't bother because the plane went down on the maiden. with the bottom mounted carb its hard for this not to happen on any plane. thank's jeff

Maybe a Cline regulator would help.Cline website

Status: offline 		I have the same thing happen on a st90. The tank is a hair higher than the carb and when the tank is full it is high enough to siphon a little out. Generally I just fill up and then fly rather than letting it sit.

Also, if the carb is all the way closed it seems to siphon a lot slower.

Status: offline 		The Cline is the way to go. With it you shouldn't need on board glow either. I've used them on two twins with good results. First start of the day will require good priming.
