So your model (mine is a E suffix) D or earlier, the whole thing is different for engagement. My motor mounts are fixed on the E model and some of the earlier ones the engine moves with a lever. I just now realized that the pictures I posted of the pulley assembly thing I made is not for your bike if the engine is tilted by the plate. There are pictures available on the web that show the detenting of the shift lever that tilts the engine. The earlier powells had B&S engines mine had a tecumseh.
