So I just went and took a look... I didn't end up cutting the nosewheel mount, but I did squeeze the motor as close to the firewall as possible. I mounted mine with the highspeed needle pointing up. The carb opening is pointing down. (when the engine is out of the plane)

Like I said earlier I did use the throttle linkage. (its actually a DuBro part)
