With the help of Neil and the lovely Viki flipped the plane.
Relieved the leading edge of the lower cowl to miss the fuel vent exit and mounted the lower cowl.
Rough cut some foam blocks to fair the fuel blister into the line of the cowling. I have seen plenty of Longez that just have the blister, without the Cozy forward elongation, so this is all I'm planning.
It seems a bit more complicated to cover the other side, with the complication of the smoke oil feed, but aligning the foam pieces fore-aft is actually easier. Hmmmm.
No pics from now on today, the camera died.
Taped cowl and fitted foam block inside NACA and lower cowl to form the lip.
