I am looking for suggestions as to what I have overlooked.

I took my new Hangar 9 Spitfire Mark II to the field today to run in the new Satio 100 four stroke and had nothint but problems.

I have mounted the engine (inverted) and fuel tank as specified in the manual. When I filled the tank I had fuek running out of the muffler and the carbuerator. I blamed it on the fact that the fuel feed line is above the carbuerator. Needles to say trying to run the engine was a problem. It was, blow the fuel out try to start the engine, retighten the prop after numerous back fires because oof the excessive fuel. When the engine started it ran fairly well but would quit when the glow ignitor was removed. I checked the original glow plug and it looked like new.

It feels like myself and several or my collegues woh were working on it have missed something. I am open to any suggestions as to what I am doing wrong. I am running the engine in the plane and not on a test stand.

Help
