Another tip to anyone that cares. When you mount the engine inverted, proper way, you tend to have fuel leaks when the tank is full and you are just sitting. This is more true with the big one than the little one, but can still be a problem on the 46. Just loop the carb fuel line to where it almost touchs the cowl on top and than back down to the nipple on the carb. This creates an air gap and lessens the siphon effect a great deal. I tried this on my 60 last night and had no leaks, NO LEAKS!!!!! And even more important, I didn't have any fuel pick up problems either. And believe me, the way I fly if I was going to have a problem I would have had a problem. This is an unbeliveable easy fix to an old problem. Try it, it works. No cost and simple. You can't beat that.
Thanks,
