okay i have my spare engine on the table to help practive aligning the clutch lever using the push rod. I took the nut off pushed the lever forward and turned the rod clockqwise until the arrows alighed on the lever arm and case mark. I put the nut on and snug it. it seems tight and when i try and push the lever forward by hand it stops at the alighing mark and doensn't engae the clutch. what do you think im doing wrong?
