Dave,
The fuel inlet is on the right side of the engine. Same side as the muffler/exhaust. The throttle connection is on the left side of the engine. They are both so close to the engine that you should not have any problem with the cowl or engine installation getting in the way. On the throttle linkage, release the spring tensioner and use a DuBro or other Ball link on the throttle lever and reduce the throttle servo travel at the Tx to about 45-50%. No other linkage is required if you just do this simple hook up.
