Hi Paul, I am thinking about the initial oil demand and have noticed the bulb below the sump in the pictures you posted. If i fill the oil tappet line before hand will that assist in the initial oil demand? I am using 1/2 hoses and there is quite a volume between the T-piece and the oil valve?
The carb is on top and i don't think i can fit it below. I am more concerned about the sideway space demand of the Revflow - it runs into the oil line from the fuel induction and the spark coil on the opposite side. But I am thinking things through, and will find a way. I have already modified the cowling for the fuel induction, so i can do that again.
Thanks again for all the advice and input - as a no-mechanical minded person i really appreciate it.
regards

Sven

Hi Sven,

I have no idea if pre filling would help or hinder things. Would the oil simply not get pushed around the engine? I think you need to be very sure that once inverted the engine will get an immediate and continuous supply of oil. If not, it will be damaged.

I do know that my own Nipper with an Acro engine once flew the length of Loch Ness (22 miles) inverted. Not me I should add!

Good luck.
