it runs fine but is difficult to
>start.
Make a cradle to allow you to invert the plane for starting. Then turn it upright to make the final adjustments.

Got a SC120 four stroke inverted in a P51 and it's no problem to start. Never had to put it the right way up!

I don't usually need to prime my inverted 4stroke engines. I close the needle valve when fueling, then open it up to start, but somewhat lean. As soon as it fires I richen up the needle to fly.

I don't bother with the needles, just heat and swing the prop.

I close the needle valves because I just use a third line into the tank to fill and then plug it off at the cowl with a fuel dot. I don't use any kind of fueling valve.
If I don't close off the needle valve fuel will run into the engine and flood it.
