bubbagates,

You didn’t say anything harsh. It is fun and educational to work out the problem both as a design issue and as an ‘adjust around issue.’ Generally speaking I find it best to remove the design issue if at all possible. Enough bad things happen without encouragement from me.

Since the beginning of time the tank/carb relationship for a 60 has been 3/8”. Generally speaking less engine tweaking is required. Also the tank relationship turns itself upside down when the airplane is inverted. Just an opinion.
