Gerry, I was not able to fly the airplane because I found myself with the problem that I cannot adjust the engine to run in the floor. Under such conditions, it was almost impossible to even make a runway test to adjust the steering.
Interesting issue about swapping one backplane screw with a nipple (hole considered).
Quick idea although good, is hard to achieve. Cline is no longer in business and the only few regulators left are in Australia, and IronBay will be the shot. Hope I do not have to reach to the Walbro.
