The four stroke, at least the one I had, the throttle was on the other side of the carb (left side if viewing from the rear). That made for some interesting linkage setup in the plane that I had that engine installed. I had to carve some of the fuselage cheek next to where the carb linkage was to make clearance.
On most 4-stroke engines you can turn the carburetor around so that the control arm is in an easier position to route your throttle pushrod to.
