Am I dreaming or is it not possilbe to flip the needle valve/throttle arm assembly on this engine? I have owned numerous OS engines over the years and I could always flip the needle valve for sideways mount, but not this one. I think I am going to throw up...

Oh, heck with it, I will just mount it upsidedown!

You cannot reverse the carb on a FL-70

Yeah, I realize that after I bought it. You would think they would mention that in their tech. notes but NOOOOOOOO!

I would think twice before inverting it. I own 4 of them and have yet to get one to run reliably inverted. They all seem to run best on their side (almost like they were made for profiles). What plane are you using it in? Is it possible to drill another hole to run the throttle pushrod on the opposite side?

ummm, mine runs good inverted
