I owned that exact motor
THats ok if your #s are right that motor will burn down soon enough. No way does it survive with that little fuel in it. We will see you in the Merc section soon enough.
How is this post still going? So obvious we are being trolled. In WHAT universe do the Ops #S MAKE SENSE!. His last post was what a gallon an hr at 3/4 throttle? I will call that for what it is BS!
Use aviation permatex to hold the gasket in place then torque it correctly. The oil was always in there you just never saw it. ALL carbs leak when you tip the motor up.
Really clearly said the box had never been off before. So ask the op if he has x ray vision. And brush up on how carbs work. And the evaporative properties of gas.
The slower you go eventually it will shift into neutral. If you keep going it will shift into reverse. Get a manual or go to a dealer and have him explain this simple process to you.
