Good question, 34-40; I should have explained. The reason I couldn't center the carb on the log is because the linkage on the carburetor would hit the manifold flange (plate) that bolts to the engine. I already had to cut part of the linkage off the carb. If I moved the log far enough away from the engine to center it under the carb, the front of it would be against the hood side at the front.
