I have an o.s. 46ax invert-mounted in a new banchee. I am having problems with flooding at an idle, and cannot adjust the carb to take care of this problem. The tank does sit higher than the carb and due to the construction of the plane I cannot lower the tank, nor can I change the engine orientation. The engine worked fine in a different plane mounted carb up. Any help is appreciated.
Tank higher than the carb--always a problem. You'll never get it to run right. Been there, done that. Tried dufferent fuel--plugs--all kinds of BS. It's all a waste of time unless you put the tank and carb CL with each other.
You most certainly CAN lower the tank. Just cut the fuse open and do it. Yank out the stock tank support and build a new one at the right height.
It's not that you CAN'T do it--you just don't WANT to. ANYTHING can be done with a little balsa and some CA. Add a couple pieces of scrap covering and your done.
Just move the tank. Your problems will disappear faster than a fart in a hurricane.
