    There is a lip on the back side of the cowling. I placed a flat pry bar underneath the cowling from the engine compartment towards the windshield and used the flat lip of the firewall top edge to pry the cowling straight up; not forward or backward but straight up. Mine was stuck with years of debris that turned to a natural glue!
