Run it inverted and it fits perfectly.

Thank you!! I will try your method. At the moment no fuel is coming to the cylinder....

Brilliant engine. I have just bought one. Thanks for sharing.

Hi I have the same plane and I wanted to share with you how i put my engine sideways. You need a Pitts style muffler and then I will look perfect and fit great! I have pics but don’t know how to send them through here. Remember Pitts style muffler and everything will fit.
