The way I did mine was to have the metal pushrod go passed the carb then I bent a 1/2'' radius 180* bend back to the throttle arm. I never had a problem with doing it this way, I've done it maybe three times, it always worked well.
You would have to rotate your carb 180 to do it that way. With the throttle in the center (as he has it) the pushrod would hit the engine.
