Sorry if I added too much complexity. But, I have an engine that has crankshaft short length and is only good for a pulley or a gear. A clutch needs more length. Doing research for a non-kit and getting specs on items and see if compatible before you buy anything is important. I don't want to have others make a similar mistake. Models numbers for engines have options for versions, this is where I erred. Still a lot of the parts of this engine are good to use on another engine I have, or sell it working as is to recoup.
