After my post about oils, it hit me about the super fuel tank that is supposed to cure all problems. As I can't get a pattern in on 4 ounces of fuel so I had to get the 6 ounce tank. Set it up like the person said to set it up. The engine a Fox 40 was running great until I pulled up for the first loop. Dead engine. So I set it richer thinking that was the problem and it wasn't. Tried leaner which was not a fix either. So I tried plugs different ranges and no help. Got out a new jug of fuel and it was a no go.
I got disgusted and went home and changed engines from the Fox to OS 40FP. Same problems. I now have a metal tank on the plane and it is working great with original fuel and plug. I have checked the super tank for leaks and can find none. So it sits on the shelf waiting for me to play with it again. Yes it is a round plastic tank that was mounted with rubber bands like I normally mount tanks. DOC Holliday
