Hi Pablo, I look forward to meeting you and sharing the joy of Nano ownership.

I also had a left exhaust flange leak. Flange was warped. I fiiled it flat and installed new gasket. No more leaks.

JK-2 Nano with Hirth 50 HP, fuel injection has a reasonable cost. It is beautiful and well built. Factory service is outstanding. Almost no cost to maintain. No Hanger needed to pay for. Inexpensive to fly. No dealing with the FAA or inspections cost. Able to enjoy flying.
