I'm putting a Zenoah G-38 in my Midwest AT-6 and have run into a couple of problems.

This is an older G-38 on which I have put a newer carb with a choke. I put the adapter on to rotate the carb to eliminate the bell crank for the throttle. I would like to put the choke on a servo also but I just can't see how to make it work. It doesn't look like you can rotate the choke arm at all and the arm is positioned such that when the choke is open it would be pulled the wrong way by the servo.

This is also my first gas engine and after reading about Tygon fuel lines it seems I need fuel barbs. I understand you can solder one on before inserting the tube into the cap on the fuel tank but don't see how you could solder the other one without melting the tank stopper.

The main reason I'm doing this is that the Saito 120 that was in the T-6 was about 2 1/2 lbs light and I hate adding dead weight. It just so happens the G-38 weighs about that same amount more than the 120.

Any help appreciated.
