G'day

I have a Saito 40a mounted inverted in a Tiger Moth. Many people told me it would not work because it has an airbleed carby AND it is mounted inverted.

Fortunately they did not tell the engine and it works perfectly. The secret is to not flood it.

I also had an OS FL70 mounted inverted in a P-40. It too ran perfectly though not for very long. Sadly, the plane did not survive its first flight.
